There's a saying in yoga: Do your practice and all is coming.
That means doing practice regularly. The key word is "regularly" - because we can't always manage "daily."
My practice includes sketching. At least a couple of times a week, I draw something. It used to be a daily thing, but I couldn't keep it up. So I opted for a few times a week, even if it's just a scribble. Once it a while, something nice happens that may turn into a painting. The point is that I don't have any plans when I open my sketchbook.
Simplicity is the removal of the useless and the unnecessary--source unknown
