I've never seen impeccable logic be sufficient to win both the heart and the mind.

You still want to be thoughtful about what you do, no doubt, but you have to learn through trial-and-error experimentation as well.

Of course if you are launching a new business you can thinking about revenues, profits, and so on, but metrics such as customer satisfaction or employee retention might be meaningful if you are focusing more internally.

The need to be thoughtful about experiment design is particularly acute within large companies, since some of the behaviors, such as having small teams and tapping into low-cost resources to maximize flexibility, won't come naturally to many people inside huge companies.

A spreadsheet for an innovative idea reports the mathematical relationship between made up numbers. You can't cash a spreadsheet.

When you are motivating people to do amazing things, you have to win over both their rational side and their emotive side.

Anytime you see a constrained market, where consumption is limited to those who have special skills or are wealthy, that signals an opportunity for innovation.
