I don't come from a traditional schooling background. My education is in studio and through self propelled projects. I try to keep momentum by
1) watching comedies
2) keeping tabs on the design world through apps like PULSE
3) reading books on design theory, mostly those assigned in colleges
4) watching tutorials on lynda.com
5) being out in the real world and not stuck behind a computer/desk all day
I also frequent Seth Godin's site for daily inspiration.
What elements in your daily quest for design/art keeps you going?
