Write Freely

Take a few minutes to put some ink down on some paper, don't restrict yourself in what you are drawing or writing, just open up your thoughts and let the pen or pencil be the guide. Do not rule out anything until after you are done and then you can sift through what you have and pick the best.

I have seen an artist doing warm-up exercises go through a ream of paper during just the hand, wrist and elbow warm up session before he even thought about really drawing something interesting. Now he always had some interesting things in those exercises but that was not the goal during the stretch.

Get the pencil on the paper and make it move around!
