I only have one why, and my challenge is to make sure the things I say and the things I do remain consistent for as often and as long as possible.

There are leaders, and there are those who lead. Leaders are those who hold a position of power or authority. But those who lead are those who inspire us. And it's those who start with why, that have the ability to inspire those around them or find others who inspire them.

If you go to the gym and you come home and look into the mirror, you'll see nothing. If you go the next day and you come home, you will see nothing. In fact sometimes you're in pain.

I cannot tell you on a day to day basis that there's a return on investment. I can tell you if you stick with it, absolutely in a few months things will start to change. It starts to change slowly. Things start to get a little easier. As the momentum builds it becomes bigger and bigger.

We pursue exercise even though empirically we see no benefit from the energy we're spending and we're hurting. So empirically we should quit. The why is exactly the same thing. You persist even though there are some short-term stresses and even though there is some uncertainty.

Any great and inspiring leader or organization that ever existed set out to do something completely unrealistic.

I find, when you're an optimist, life has a funny way of looking after you.
