No one should ever be afraid ...

No one should ever be afraid of failing; it’s being afraid to give it your all in trying that I urge against. If there is one thing I have learned, particularly in my life as an athlete, it is that our limits may not be where we think they are. And, even when we think we’ve finally reached them, the next time we go there exploring we often find that they’ve moved again.

Quotes from the same author

We all have talents that, sometimes, we never quite fulfill. We're all scared, deep down, but maybe we just need to lay it on the line and explore our abilities and just not be afraid of failing.

The key is to trust in your preparation. You have done all you can, so focus on that fact. You will remain the same person before, during and after the race, so the result, however important, will not define you. The journey is what matters.

Pick your battles, and accept yourself for who you are.
