No vision is worth the paper it's printed on unless it is communicated constantly and reinforced with rewards.

Any company trying to compete...must figure out a way to engage the mind of every employee.

There are only two sources of competitive advantage: the ability to learn more about our customers faster than the competition and the ability to turn that learning into action faster than the competition.

Nothing is worse than the person in their 40s who says, 'I'm not going to learn this.' 'I don't carry an iPad.' That will label you and put you right in the corner. Some people do it as a badge of honor. I've seen them myself, they walk around bragging [about not knowing much about technology].

In real life, strategy is actually very straightforward. You pick a general direction and implement like hell.

On the face of it, shareholder value is the dumbest idea in the world.

When all is said and done, teaching is what I try to do for a living.
