The time is a thing; you don't have so much time. A good trick is to try and think about a way to use material from one occupation for the other. It's like going through working a day job, this is so dumb to say, but you know how Julian Schnabel made those crockery paintings while he was working as a short-order cook? It's like that, using what is around, transforming that to create meaning and make art. Trying to take nothing and make... something.
