I've tried lots of things but haven't finished any.
coliveira: It looks like you're good at finding the wrong side of everything you do. Just look at the bright side. You did a lot of impressive things. Nobody is successful in more than a small percent of what they do.Moreover, in every success there is always some way to find flaws (it was too easy, nobody cares, I didn't learn anything....). So, you have to take yourself lightly, continue to work hard, and enjoy the things that you do. Try to define success for yourself, not for others.
