I like to say, "Failure is just another chance to try again."
If you aren't willing to risk failure, you'll never try anything new. Everyone starts out at the bottom when doing something new; mistakes are expected and nothing to be ashamed of. If it's worth trying, then it's worth failing at. Go ahead and try it! It doesn't matter if you don't progress as rapidly as others. Take your time to learn the basics. Ask questions. Enjoy yourself. Focus on your own progress rather than comparing yourself to others. Often, you will be your own worst critic, so listen and believe when others praise your work even when it looks like crude compared to what you imagined.
And, even once you reach mastery of a skill, realize that flubs will happen and bad days occur. Such is life. But don't worry: failure is just another chance to try again.
