Appropriate complexity and risk

The best time to experiment in the kitchen is if you don't have 11 guests coming for dinner in three hours.

We often sign ourselves up for long, involved entanglements, and a good thing, too, because they can enable us to produce real value.

But our promises matter, and there's no need to raise the stakes at the same time that we're figuring things out. 

Professionals leave themselves an out.
