Lynda Barry's Principles of Creativity

the thinking part of you is not the doing part of you or the experiencing part of you
the thinking part of you can tell you that a decision has been made but it's not the part of you which decides things
this is why thinking is not the same as creating though the thinking part of us seems completely unaware of this

I took this from page 207 of Lynda's book "What It Is" on creativity, writing and creating art in general. It's a wonderful book and she is absolutely right. She advocates that writing (or drawing) is a physical activity, not a thinking activity. If we stop to think while creating art, we lose the creative impetus we had in the beginning and end up over-analysing things and, inevitably, becoming too critical of what we've just written/drawn. So, relax, focus on what you are about to do, and then do it - no thought, no analysis, nothing. Set yourself a time to do the writing/drawing and then put it away. Feel free to come back and have a look and correct things later on, but while you are doing it, just do it, nothing else!

What I don't agree is when she goes against creating art in a computer, as she says it's not physical enough to keep the momentum going. I differ on this as I quite often find myself running my fingers over the keyboard while waiting for the inspiration to surface, in the same way she will draw spirals or write the alphabet. In this way, my fingers kind of move spontaneously, expecting the "doing part of me" to tell them what to type. I guess that Lynda doesn't have typing fingers so she can't relate to this, but that's how it works for me.

And here's a chow-chow dog I drew earlier... on the computer!
