Someone who tried 10 things and only has 20% success rate... produce more results than a person who tried 0 things and has a 100% success rate. Next time when you made a mistake or you "failed" at something or you got rejected, that's admirable because it means you are trying to make things happen. I don't know of anyone that succeeds in everything they do the first time. They just don't let things stand in their way and I hope you won't either.
