Getting Things Done: the art of stress-free productivity

by David Allen

Your ability to generate power is directly proportional to your ability to relax.

If your mind is empty, it is always ready for anything; it is open for everything.

Anything that does not belong where it is, the way it is, is an “open loop,” which will be pulling on your attention if it’s not appropriately managed.

You must use your mind to get things off your mind.

The idea of “mind like water” doesn’t assume that water is always undisturbed. On the contrary, water engages appropriately with disturbance, instead of fighting against it.
