Mental Strength in Sport & Life: Overcoming Nerves and Self-Doubt
Written by Michael Clark, Registered Osteopath and Co-founder of Clarks Healthcare
Nerves are something everyone faces at some point. In the competitive world of sports, avoiding anxiety isn’t an option. There’s no escaping the pressure, and to truly reach your potential, you need to find ways to manage nerves—and even use them to your advantage. Having treated professional athletes for over 20 years, I’ve heard countless insightful stories and learned practical mental exercises that help shift focus and calm the mind.
In this article, I’ll share insights from the athletes I’ve treated, my own personal challenges competing at a high level, and practical wisdom from Stoic philosophy. Whether you’re preparing for a rugby match, a Jiu-Jitsu competition, or a major exam, these lessons can help you approach challenges with confidence and resilience.
I’ve come to understand that despite the seemingly cool composure of opponents, almost everyone deals with nerves and self-doubt before an event. Personally, I remember sleepless nights and even physical sickness from anxiety. Imposter syndrome was always lurking, making me question whether I truly belonged.
It took me a long time to realise that much of my anxiety stemmed from a desire for control. I wanted to guarantee success—whether it was winning a competition or passing an important exam—but the truth is, that’s impossible. What I learned over time was to let go of the things I couldn’t control and instead focus on shifting the odds in my favour through diligent preparation. The outcome was never something I could dictate; the only things I could truly control were my thoughts, actions, and effort.
This shift in perspective made all the difference.
Training and Preparation: Control What You Can
This is the first and most critical lesson: control what you can. Focus on what lies within your control and let go of what doesn’t. In sports, this means preparing to the absolute best of your ability. Train hard, listen to your coaches, develop your strategy, study your opponents, and focus on what you can improve.
When I was competing, preparation was non-negotiable. I spent countless hours training to be as fit and skilled as possible, ensuring I was physically ready. Losing because of fitness was never an option for me. But preparation wasn’t just physical. I devoted vast amounts of time to studying techniques, visualising success, and mentally preparing for competition.
I’ve similarly heard countless stories from athletes who say the most effective way to alleviate nerves is to become almost obsessively focused on preparation. Set clear, achievable goals for yourself. Work not only on your physical conditioning but also on your mental game. Break down your training into small, manageable steps, and focus on mastering each one. Trust the process and know that your hard work is building a solid foundation that, over time, you’ll see the fruits of your labour.
It’s easy to fall into the trap of avoiding what really needs to be done—whether it’s training, revising, or conditioning. Waiting for the perfect moment, or endlessly planning without actually doing the work, is a mental trap. But when you commit to the process and leave no stone unturned, you’ll experience a sense of calm and confidence. Even though you can’t control the outcome, you can walk into any competition knowing you’ve done everything possible to succeed.
Visualisation: Rehearse Successes & Challenges
Visualisation is a powerful tool that can help you feel fully prepared. Personally, I would regularly close my eyes and mentally walk through an entire event, from start to finish, in fine detail. I’d visualise everything going perfectly, allowing myself to showcase my hard work. But I didn’t stop there—I also incorporated negative visualisation. The Stoics called this premeditatio malorum, or “the premeditation of evils.” This technique involves mentally rehearsing the challenges you might face and how to respond to them, so you’re better prepared to handle them if and when they arise.
In the lead-up and just prior to every match, competition or exam, take the time to visualise both successes and obstacles. Picture yourself performing at your best—whether it’s making the perfect tackle, scoring a try, or securing a submission. Visualise the event as vividly as possible, including how you’ll respond to setbacks or unexpected difficulties. The more you rehearse these moments mentally, the better prepared you’ll be.
This practice helps build confidence and reduce nerves, ensuring that when the pressure is on, you remain calm, focused, and composed.
Control the Process, Not the Outcome
In sports, as in life, you must accept that you can’t control the outcome of a match, competition or exam. While you can shift the odds in your favour through preparation and the effort you put in on the day, you can’t control external factors—the weather, the referee’s decisions, injuries, your opponent’s performance, and countless other variables that we call fate.
This was a hard lesson for me to learn. As someone who struggled with nerves and self-doubt, I wanted to guarantee success. I’m a natural control freak, but the more I tried to control the outcome, the more anxious I became. It wasn’t until I learned to let go of the outcome and focus on the process that I started to find peace and perform at my best.
Before a match, competition or exam, remind yourself of the things that are within your control: your preparation, your effort, and your mind-set. Focus only on these elements, and let go of everything else. By doing this, you’ll find not only greater confidence but also a clearer path to success.
Stepping Outside Your Comfort Zone
Staying within your comfort zone is one of the biggest mental traps that will hold you back in life. Overcoming nerves and self-doubt takes time, effort, and, most importantly, exposure—repeatedly facing the things that make you anxious until they no longer hold power over you.
The same principle applies in sports. The more you expose yourself to high-pressure situations and step outside your comfort zone, the more at ease you’ll become. Competing in matches, performing in front of crowds, and managing the pressure of high-stakes moments will all get easier with experience.
It’s a straightforward process that can be applied to any fear. I used to be afraid of heights, so I earned my AFF skydiving licence. I was terrified of sharks, so I went cage diving with great whites. Public speaking made me anxious, so I did it over and over again until the fear disappeared. Every time I faced my fears, they shrunk, and I grew braver.
Don’t shy away from pressure. Seek it out. Compete as often as you can, even if you’re nervous. The more you put yourself in these situations, the more comfortable and confident you’ll become, both in sports and in life.
Breaking Free from Self-Doubt
In sports, only a small percentage ever reach their full potential, and more often than not, it’s crippling self-doubt that holds them back. Honest reflection is important, but many athletes unknowingly lose a match before it even begins. Professional fighters often defeat themselves before stepping into the ring. It’s a built-in self-preservation mechanism where fear causes them to hold back without even realising it.
I remember this vividly when my coach told me that I wasn’t losing because of a lack of skill—I was losing because of a lack of belief in myself. He was absolutely right. I had been unknowingly getting in my own way, holding back when I needed to push forward. That realisation changed everything for me. I stopped holding myself back, and I started winning everything. It wasn’t because I had suddenly become the best—it was because I finally believed in my ability.
If you struggle with self-doubt, focus on building confidence through preparation. Remind yourself of the work you’ve put in and the skills you’ve developed. Trust your coaches and in your abilities, and know that you’re capable of far more than you think. Once you stop doubting yourself, you’ll exceed your expectations.
Accepting Adversity
In sports, as in life, adversity is inevitable. There will be bad calls, injuries, unfair decisions, bad luck, and disappointing losses. But rather than letting these setbacks defeat you, learn to embrace them as opportunities for growth.
Every challenge you face is a chance to build resilience, to learn, and to improve. In fact, we often learn more when things go wrong than when everything goes perfectly. As Marcus Aurelius wisely said, “The impediment to action advances action. What stands in the way becomes the way.”
When adversity strikes on the field, don’t allow it to discourage or fluster you. Use it as fuel to get better. Whether it’s a bad call, a tough loss, or a personal mistake, view it as an opportunity to learn and make improvements. Remind yourself that challenges are a necessary part of the process. By embracing adversity, you grow stronger—both mentally and physically. Keep pushing forward, and use every setback as motivation to refine your skills and continue improving.
Practising Gratitude: Stay Grounded
It’s easy to get caught up in the pressure of competition and forget how fortunate we are to be able to compete at all. Practising gratitude can be a powerful way to stay grounded and keep things in perspective.
Before every match or competition, take a moment to reflect on the things you’re grateful for—your health, your teammates, the opportunity to compete, and the support of your coaches, teammates, friends and family. This simple practice can help alleviate nerves and remind you that win or lose, you’re fortunate to be doing what you love.
The Stoics believed in the power of gratitude. They taught that we should appreciate the present moment and the opportunities we have, rather than always striving for more. By practising gratitude, you can shift your focus away from the pressure of competition and onto the joy of the game.
Always a Student: The Power of Lifelong Learning
We live in a time where access to knowledge is almost limitless, whether through books, online platforms, or great coaches. Cultivate an unquenchable thirst for knowledge, because the pursuit of learning never truly ends.
To excel in any aspect of life—whether in sports, your career, or personal growth—you need to surround yourself with people who are better than you. This mind set of being a “forever student” has profoundly impacted both my competitions and my personal journey. I always strive to train with those who challenge me and study under coaches or tutors who are more knowledgeable. Surrounding yourself with people who push you to improve is one of the most valuable things you can do.
Additionally, be open to honest feedback. It can be tempting to shy away from criticism, but feedback is a gift. If you’re not receiving feedback, actively ask for it. Approach your coach or trainer and ask, “What can I do to improve?” Even top UFC fighters who have just won world titles go through a detailed review of what went well and what needs improvement. It’s this constant hunger for growth that keeps champions at the top. By embracing constructive feedback and applying it, you accelerate your progress beyond what you thought possible.
Adopt a mind-set of lifelong learning. Surround yourself with individuals who challenge you to be better, and don’t just seek out praise—actively seek feedback and use it as fuel for continuous improvement.
Managing Pre-Competition Nerves
Pre-competition nerves are a natural. No matter how experienced you are, those butterflies in your stomach will always be there. But learning to manage them can make all the difference between performing at your best and crumbling under pressure.
One effective way to control your nerves is through deep, controlled breathing. This simple yet powerful technique helps slow your heart rate and clear your mind. Before your next big event—whether it’s a match, competition, or exam—try this: inhale deeply for a count of four, hold for four, and exhale for four. Repeat this process until you start to feel your nerves settle.
As you step onto the field, enter the ring, or walk into the exam hall, focus on being fully present. Don’t let your mind wander to outcomes like winning or losing. Stay grounded in the moment, concentrate on the task at hand, and trust the hard work you’ve put into your preparation. At that point, all that’s left is to give your best, staying calm and focused throughout.
Conclusion
Whether you’re gearing up for a big rugby match, a martial arts competition, or a critical exam, mastering the mental game is just as crucial as physical preparation. By embracing key principles like focusing on what you can control, visualising success, letting go of what you can’t control, and embracing adversity, you can build the mental resilience needed to perform at your best.
Remember, it’s normal to feel nervous or uncertain—nerves are simply a sign that you care. But with the right mind set and thorough preparation, you can channel those nerves, perform with confidence, remain calm under pressure, and even exceed your own expectations.
Best of luck, and always remember: control what you can, and let go of the rest.
