Write more. Draw more. Paint more. Try harder.
What else? Work-out more. Our metabolism has slowed down a LOT. It kinda sucks. Oh and quit smoking.
Otherwise, no worries. Don't stress so much. Things will work out. Trust me.
I would be too afraid to say anything else, to be honest. I'm not even sure I'd say anything here I've written. I wouldn't want to fuck up what I have now. My life is awesome.
