"Where do you put the tired?"

I'm reading a fascinating book - Linchpin by Seth Godin. On page 65, he references long distance runners and men building railroads and asks, "Where do you put the tired?"

The ability to work through the fatigue, or as Seth also notes, the fear, is a key to becoming a hard worker. But what can you do to keep going and push through the fatigue? What separates those who stop from those who don't?

The Challenge: Go a little farther today than you did yesterday. Not much farther. Run an extra 25 feet. Make an extra phone call. Pick up a piece of clothing you would have left on the floor.

The breakthrough comes after a thousand tiny hits.
