Sell sell sell

I love painting. It's just a little release for me. Makes me calm, I like the addictive feeling you get when you cant stop, you feel yourself being absorbed and you can't leave it.
My dad thinks I should start to sell based on a paint I've done hanging on my living room wall. I don't know if its a proud father reaction or whether I should take the leap and pit myself on the line. Lots to think about.
