Do you remember the first painting you sold? Do you remember the first big painting you sold? How about when your friend hung your painting and called you over to see it?
Those are amazing feelings for me.. The feeling that someone really likes your art..enough to purchase it from you and hang it in their space.. it never gets old. Those emotions outweigh SO MUCH anything you feel when you buy generic art, at say, Ikea to hang at home.
You can make your own art...and you'll love it. What are you waiting for?
