Dashboard
Persistence is key to improvement. Persistent practice drives improvement. I keep a pad in my car so that I can practice drawing. Having a pad and pen handy eliminates any friction. While waiting for tennis, I pulled out a notepad and a pen and sketched my dashboard.
A simple drawing of my dashboard helped me work on perspective, circles, and spacing. All because I have a pad and pen in my car.
How can you improve your persistence by eliminating some friction?
