Hell yeah or no.

High performer and brilliant mind Derek Sivers invented a genius cure for overcommitment:

When you've got a decision to make, if you don't think HELL YEAH! at the idea, then say no.

If you say no to almost everything, then when a truly incredible opportunity comes along that makes you think HELL YEAH, you have the time, energy and space in your life to fully commit to it.

Too many of us take on far too many things at once to function at peak performance.
Say hell yeah, or no.
