When I find myself feeling cast down, it's usually because I've been away from the hum and crush for more than 12 hours. The energy of this city is addictive and contagious- I feel like my previous level of pushy workaholic freak comes in somewhere on the low end of the spectrum in relation to all the others doing the crosstown stomp.
When I need a quick pick-me-up, I like to head in to GCT and draw the people passing through. Not only do I see many inspiring outfits, I also get quite a lesson in posture/attitude/gait, a boon for both the actor and visual artist portions of my brain.
I love the challenge of communicating a personage in less than five seconds, and one and two minute poses are always my favorite part of any life drawing class. In those sparse seconds there is no time to fuss over getting it right; all that matters is spatial relationships and movement. Well, really that's all that matters in art (to me), but there is greater freedom to fail when time is a limited resource.
Drawing people on the subway is another good game, although one that has to be undertaken with some caution. There are all kinds of crazies on the 4 train, and I am not afraid of being mistaken for one: I am more afraid of attracting their attention. It's good to draw when the carriage is sparsely populated, and all persons are sleepily disinterested.
