“No business can continue to shrink. That can only go on for so long before irrelevancy sets in.”

“The single best way to develop leaders... is to take people out of their safe environment and away from the people they know, and throw them into a new arena they know little about. Way over their head, preferably. In fact, the more demanding their challenges, the more pressure and risk they face, the more likely a dynamic leader will emerge.”

“People calculate too much and think too little.”

“We are stubborn on vision. We are flexible on details.”

“Maintain a firm grasp of the obvious at all times.”

“We need big failures in order to move the needle. If we don’t, we’re not swinging enough. You really should be swinging hard, and you will fail, but that’s okay.”

“Humanity is at a crossroads. We can continue down the current path of greed, consumerism, oligarchy, poverty, war, racism, and environmental degradation. Or we can lead the world in moving in a very different direction.”
