Sell the Character
When Andy Warhol was painting Arnold Schwarzenegger in his Soho warehouse he would always talk about the most important thing for an artist. It wasn't selling the art. It was selling yourself. You have to become an interesting person. The parties you go to, the people you hang out with, the photos you take, what you publish all crafts your character. It fascinates people enough to give you attention which draws attention to your art. The wave Andy Warhol's character created was the result that drove his paintings to be worth millions of dollars.
