Should be the mindset of every athlete! You have to think that yes I can do it! Don't underestimate or sell yourself short. You can it!
Don't let your athletic preparation become stagnant. Keep learning, working hard, stepping out of your comfort zone, and trying to get better! And always seek out feedback.
In sports, what separates the best from the rest? One's ability to manage emotions and keep your composure when the pressure is on, really is the difference. The most successful perform their best under pressure. Instead of dreading pressure, they love every second of it. This is why your mindset is HUGE in sports. With a confident and strong mindset, you less likely to "choke" under pressure and instead perform at your best. Developing a strong mindset might be the missing piece you need to reach your potential!
Too many times I hear athletes getting too preoccupied worrying about the other competitors. You have to focus on you, worrying about the other competitors just causes you stress, which will impair your performance. You also can't control how the other competitors act, play, or perform. You really have to focus on being the best you can be. Focus on you and performing to the best of your ability. Don't worry about anyone else.
Think back to your best performance. What were some of the little moments that helped you get there? Sometimes it takes much persistence, hard work, and not giving up to get to that big moment. So, be proud of those little moments. At your next competition, remember the little moments that got you there.
