Do not be afraid to try. it's not always about winning or achieving, it's on how you do it. If there is nothing to win or lose then at least you gain experience. 

It's okay to make mistakes. There are rooms for improvement. Believe in second chances. Life is full of surprises.

The happiest feeling is not success. Believe me. When you are successful you will always look back. You will narrate the road and the way  you achieve success.

Believe in yourself. You can do it.
