Doodling fits those short empty time slots in the day.  No goals.  No accomplishments.  Just being in the moment with pen in hand.

“Rest is not idleness, and to lie sometimes on the grass under trees on a summer’s day, listening to the murmur of water, or watching the clouds float across the sky, is by no means a waste of time.”
— John Lubbock, The Uses of Life
