I've tried lots of things but haven't finished any.
akamaka: You don't have to be successful at anything.I spent most of my twenties dwelling on my failures and wondering what I was doing wrong.  I wish someone had just told me to chill out and do what I enjoy, but nobody did.You seem to have a lot of curiousity and willingness to try knew things, which is awesome.  If you can come out of your twenties as a person who is healthy, learned, and experienced, you have accomplished a lot.Tomorrow, forget about all the past endeavors you've mentioned, and just go out and have fun and try something new.
