Be Excellent at Anything:

Be Excellent at Anything makes a compelling case for a new kind of workplace, a better way of working and a more deeply satisfying way of life.

In fact, we're designed to pulse. We're more productive and more satisfied when we move rhythmically between spending and renewing our energy across four dimensions:
Physical, Emotional, Mental and Spiritual.
