When I was a book illustrator most of my time was just making dots. Either with a pen, a brush, a chisel or a stylus. Tiny tiny dots or scratches that looked like dots.People seemed to like the end results (the creative bit was in the planing which presumably someone else proscribes to you in a professional setting). I like a certain amount of repetition in my life but that aspect was a bit of a chore.
I constantly doodle. I’m lucky to be able to draw with either hand so I’m never away from a pen and a piece of paper. It does add to my tendency to typo though. Other people colour in or write poems while they do something else. Counter to what I was told at school it’s now been proven to aid concentration.
