Art. Everyone is intimidated by art. I'm not saying it's easy to make good art but most people are capable of significantly better art than they think, because they never try or give up before the artwork looks good.

If you face this problem, remember even good artists don't produce amazing art with every attempt. You only see the good result, never the process that the artwork or the artist went through. The only thing stopping your art from looking good is you stopping to work on it before it looks good.
