The secret of change is to focus all of your energy, not on fighting the old, but on building the new.

First they ignore you, then they laugh at you, then they fight you, then you win.

Deciding what not to do is as important as deciding what to do.

Early success is a terrible teacher. You’re essentially being rewarded for a lack of preparation, so when you find yourself in a situation where you must prepare, you can’t do it. You don’t know how.
