From The Guardian: Don’t Give Up the Day Job (a UK perspective).
How does the average artist make a living? If you’re Damien Hirst, of course, you need only flog a couple of sharks in formaldehyde; if you’re Tracey Emin, an unmade bed will do. If you’re an actor, a well-publicised turn as Hamlet and near-omnipresence in the Christmas TV schedules, a la David Tennant, would keep the accountant happy.
But none of these scenarios will ring true for the average artist – who is more likely to be stacking supermarket shelves, waiting tables or writing advertising copy by day, and acting, dancing or sculpting by night.
