Gotta hit it right away, man. In my experience, if you just sit and trudge through the block, something amazing will come out. I hit a funk, and sit and just try and draw threw it. I want to pull my hair out and blow up my computer, but right when I'm ready to quite art entirely, I lay down a couple more lines and BOOM...magic. It just happens that way for me, and a ton of people I know. Just stick with it man. You'll blow up if you just slap that stump in the face.
