I draw all the time now.
I have notebooks of every size. There’s always some kind of notebook in my purse, but if somehow my notebook has escaped from the purse, there’s always something else to draw on — a calendar or a scrap of paper. I didn’t used to draw as much and as freely as I do now. I regret that lost time since I get so much enjoyment from drawing, and the only reason I didn’t pursue it constantly in the past was inhibition.
The sooner you rid yourself of that inhibition, the better.
Notebooks are for thinking. The thoughts can be careful. Or they can be spur of the moment, stream of consciousness, blurry, furtive, haphazard, tentative, carefree, rapid, or exuberant.
Some of my favorite drawings are hidden inside notebooks.
A lot of wonderful memories are hidden there too.
