Marketing is about spreading ideas, and spreading ideas is the single most important output of our civilization.

Realize that your physical experience and environment is the materialization of your beliefs. If you find great exuberance, health, effective work, abundance, smiles on the faces of those who you meet, then take it for granted that your beliefs are beneficial. If you see a world that is good, people like you, take it for granted again, that your beliefs are beneficial. But if you find poor health, a lack of meaningful work, a lack of abundance, a world of sorrow and evil, then assume your beliefs are faulty and begin examining them.

The scalable, profitable strategy is to change the game, not to become the most average.

The only thing that makes people and organizations great is their willingness to be not great along the way. The desire to fail along the way to reaching a bigger goal is the untold secret of success.

The Internet is going to change marketing before it changes almost anything else, and old marketing will die in its path.

It's never too late to redefine self-control, to change long-ingrained habits, and to do the work you're capable of.

You create your own reality. There is no other rule.
