“Success is more about what you say NO to than what you say YES to. You can completely destroy your personal energy by saying yes to the wrong types of things.”

“The first thing you’ve got to do is tell yourself that the shitheads are wrong…Not just a little bit wrong, but irremediably, absolutely, and endemically wrong. Nothing you can say or do will stop their being wrong. They’re damned to eternal wrongness, and that’s God’s will.”

“We live in a society where there is no law in making money in the promulgation of ignorance or, in some cases, stupidity. There are a lot of things you can say never happened.
