Nothing in the world is more common than unsuccessful people with talent, leave the house before you find something worth staying in for.

But there's no way round it-commercial success is a mark of failure for a graffiti artist. We're not supposed to be embraced in that way. When you look at how society rewards so many of the wrong people, it's hard not to view financial reimbursement as a badge of self-serving mediocrity.
