Marc Lesser in Less: Accomplishing More by Doing Less:

One of my teachers was Harry Roberts, a Yurok Indian-trained shaman, naturalist, cowboy, and Irish curmudgeon, and one day he asked me, “Do you want to know the three most important tasks of a human being?” I didn’t hesitate to answer yes. “There are three tasks that matter in this lifetime,” Harry said.

“The first task, though not the most important task, is to quiet the busyness of your mind. The second is to find your song. And the third task is to sing your song.”

Well put.
