Everything in life that you experience has it's own good and bad points. From a strand of hair to the end of this universe. Just as there are many truths, there are also plenty of ways you can look at things. You can look at rejection as something that it will bring you down..... depriving you of what you did, seeking your weakness which will lead to your surrender to your current pursuit that you've worked so hard for..... or you can look at it in a way that it will motivate you even more to find your own answers, proving all of those who didn't believe you wrong. I don't know whether that answer exists for everyone, but there's only one thing I know..... that 'success only comes to those who presevere in doing what they do best'. Don't ever give up, never surrender, always fight for your beliefs, leaving something valuable that humanity will cherish..... that's the only way to distinguish yourself..... that's the only way to prove your own existance..... and that's the only way that you will ever matter.
