The more often you fail the more quickly you start succeeding.
Don't be afraid of failure, what might initially makes you uncomfortable may give you courage and wisdom to win something big.
Accept failure as a part of success, most successful people fails quite often, its like hit and try thing, the more you try the more your chances increases for a hit.
Here I want to give you an example of great Spanish painter Pablo Picasso, he made more than 50,000 arts in his life time (including paintings, drawings, prints, sculpture, and ceramics) which means he must have tried many things in life.
But he is mostly remembered for around 63 of his works.
Can you imagine the rate of success in his case?
So, don't be afraid of failure or not touching up to the mark.
Just keep doing what you are good at.
“An essential aspect of creativity is not being afraid to fail.”–Edwin H. Land (Scientist and Inventor)
