This morning I felt some reluctance to sit and do the drawing.  I think the process has become a bit flat because I have approached each drawing from the same idea, or something like that.

In any case, the prominent feeling was "Do Something Different," which naturally made me feel self conscious and discontented with the end product.  

Is it counter productive to push yourself out of your comfort zone when doing something that is meant to be impulse-by-impulse, or does the push eventually lead to more interesting places?

I guess that is the whole point of the experiment.  Or one of the whole points.
