Is good enough actually good enough?

How much more effort does it take to go from 90% proficiency to 91%?

Attention, focus, and energy are all finite resources. We have to spend them wisely and decide which goals are worth pursuing.

By saying yes to some things, we have to say no to others. Every job worth doing is sometimes worth doing well. Which ones worth doing is up to you.
