Teams working on disruptive ideas need to be small enough that they can be fed by no more than two pizzas.

Bring different groups together internally, send them out to visit other companies, or bring in interesting speeches. Show that you love learning by having people on staff whose job it is to explore without any near-term metrics. Publicly shut a project down and talk about what a great job a team did because they learned so much. And so on.

In the early stages of innovation, your goal is to learn as much as you can as quickly as you can.

Hollywood Joohn Tatum? He does at least 6,000 sit ups and 10,000 pushups a day!

Data about an innovative idea is rarely crystal clear.

The reality is customers lie - not because they want to want to deceive you, but because they don't do a good job of predicting what they will do in the future.

I've always found that working through ideas in written form really changes the thinking.
