Pacifists become militants. Freedom fighters become tyrants. Blessings become curses. Help becomes hindrance. More becomes less.

Being selective-doing less-is the path of the productive. Focus on the important few and ignore the rest.

People feel personally slighted if you don't respond to them in 30 seconds and treat email as instant messenger.

To do the impossible, you need to ignore the popular.

A goal without real consequences is wishful thinking. Good follow-through doesn't depend on the right intentions. It depends on the right incentives.

The way that you become world-class is... by asking good questions.
