It's been a while, I've been working lately on some stuff I can't post quite yet. In the meantime I would admonish you to check out the incredibly talented Joe Bluhm's new sketchbook. It's chock full of some great drawings and quotes from a number of artists on the benefits of keeping a sketchbook.
Also on the inspirational quote front, I really like some of the quotes Stephen Silver has put up in this Facebook group. Always a good read.
