In art, as in life probably (damn), sometimes you don't have to have each and every step mapped out before you move. (Although we all would like to.) Sometimes you know only the step directly in front of you. Sometimes the solution to confusion about your art, is to pull out your crappy photocopies and draw some crappy (but less crappy than before) sketches. And it reminds you that the process is a huge part of what you're enjoying even when you have no idea about any kind of product.
Above: Top left is a sketch I did back in the summer. The other three are yesterday's. The latter three may not look a whole lot different, but they felt very (very) different to draw. They felt better, and that in itself is incentive to keep going.
