The top 25 at every company really set the tone. Everyone watches them. They need to be present and focused. No slackers at the top. They need to meet in combination every recruit. They need to meet them on the first day. They need to teach by example. This is the lesson that great companies teach.

The choices we make define our future.

You need to have sufficient resources against your priorities. Your eyes have to be open every day.

A curious mind does not jump to conclusions but tests carefully and thoroughly. A curious mind will draw on all of life's experience to get to the big "uh huh." The curious cut the data by quintile, by segment, and by user.

A lot of people believe you only need a vision. This is simply not correct. You need brilliant execution every day. It's about attention to all the details of go to market.

Own one idea. Complete it. Map the current model of purchase and usage. Change how it is done so at least some part of the market uses only your product. Extend from that core user to a much broader universe. Describe your concept in a very short, "six-word story" - a la Ernest Hemingway: "For sale: baby shoes, never worn."

All companies have many opportunities. Strategy is about allocation of resources and priorities.
