Find something you enjoy doing (love), and do it. Take a step back and asses - Do you really really love working 12 hours a day? If not, then stop doing it.
If you're working 12 hours a day in the hope that some day it'll all pay off and you'll then be able to do things you love, then that's utter bullshit and you're probably deluding yourself.
Find things you love doing, and do them. Now.
