• Never use a credit card for credit. The only kind of credit, or debt, that is acceptable is debt to acquire something whose exchange value is extremely likely to increase, like in a home. The exchange value of most things diminishes or vanishes the moment you purchase them. Don’t be in debt to losers.

• Pros are just amateurs who know how to gracefully recover from their mistakes.

• Extraordinary claims should require extraordinary evidence to be believed.

• Don’t be the smartest person in the room. Hangout with, and learn from, people smarter than yourself. Even better, find smart people who will disagree with you.

• Rule of 3 in conversation. To get to the real reason, ask a person to go deeper than what they just said. Then again, and once more. The third time’s answer is close to the truth.

• Don’t be the best. Be the only.

• Everyone is shy. Other people are waiting for you to introduce yourself to them, they are waiting for you to send them an email, they are waiting for you to ask them on a date. Go ahead.

• Don’t take it personally when someone turns you down. Assume they are like you: busy, occupied, distracted. Try again later. It’s amazing how often a second try works.

• The purpose of a habit is to remove that action from self-negotiation. You no longer expend energy deciding whether to do it. You just do it. Good habits can range from telling the truth, to flossing.

• Promptness is a sign of respect.
