I can totally identify with the artist here when it comes to drawing in free time, I get paid to draw every day and am forced to be creative almost hourly and with deadlines and the pressures of commercial applications I sometimes draw for days non-stop. So when a friend calls me up and says "let's hang at the coffee spot and sketch a bit" I think 'ok why not', then I sit there and stare into a blank page/tablet for hours unable to even begin to think up something to draw and quite honestly not wanting to. I used to draw on walls and cars and shirts and every open space and it would be immensely rewarding, now I barely have time to appreciate what I produce even though it's some of me best work ever lately. Oh well - just something for budding artists to keep in mind
