Pencils for an illustration I may or may not finish.
One of the challenges of parenting for me is maintaining enthusiasm for creative projects. I begin with a lot of energy and excitement, but where I used to just sit down and work on something for several hours/days until it was done, I now must work in small increments, stopping and starting over and over. After stoping and starting five or six times, it feels (even if it's not true) that the art is going nowhere and I should probably just start something new.
Writing seems to be the one exception to the rule, thank goodness. And I think it's because even if I can only sit down for a half hour, I can still knock out a couple of pages and create something that, even if needs polish, still feels complete.
