It could go either way, couldn't it? If it's a difficult subject we can drive ourselves crazy trying to do it right - make it good enough. Then we raise our blood pressure and wear out our erasers. I think it all depends on the reason we're drawing - are we drawing for the fun of it, or do we really need a good rendering of the subject. One reason is just as valid as the other, but we seem to have to give ourselves permission to just draw for fun.
Forty-three degrees here right now! That is something like sixty degrees warmer than it was a few days ago!!!
