I didn't think about it before I started, but my almost daily practice of Sumi ink sketching has laid a golden egg! More than 300 ideas for abstract paintings and design! Just 10-20 sketches most days wasn't too big a project, yet repeated again and again, it's become quite a nice stack of ideas.
I have a similar feeling when I start a new sketchbook at the beginning of a trip. I don't know how it will turn out, but I commit to daily drawings, daily comments, daily facing a page and designing something unique. At the end of the trip, I have something amazing.
If I were to think about the end result when I was just at the beginning of either of these efforts, I think I would get overwhelmed or nervous about doing things perfectly. Grandly. Beautifully. But, by keeping my focus on one day, one set of sketches (really, 10-20 is not too much to tackle), or one page in a sketchbook, I have bite-sized bits that are easily done.
And a sweet reward for consistency.
Maybe that's why the tortoise wins the race in old Aesop's fable. Slow and steady. Not a bad way to tackle things.
