Balancing art time with day job?

[nickzornart]

So I'm having a pretty tough time right now balancing working on portfolio pieces (to try to get a job in the entertainment art industry) and working my day job. I work in a pretty stressful position at a local hospital from 9 - 6 Monday through Friday, so when I get home around 630 I'm pretty wiped out, and have a hard time getting stuff done. I work on art all weekend, but that's also when I have to get all of my normal living stuff done too, so I'm finding my output is pretty limited. Anyone have any ideas how to increase output and balance work and art?
