The best way to think is to move

I don't know why, but creative thinking and planning with clarity and ambition are always helped by motion. 

Go for a walk. Hike on a trail. Take a road trip. Fly to another country. 

The act of moving helps you unstick yourself, and breaks you out of the doldrums and hesitancy that can hold you back.

If you want to get things moving in your life, then get moving.
