Investing isn't about beating others at their game. It's about controlling yourself at your own game.

There is no reason to feel any shame in hiring someone to pick stocks or mutual funds for you. But there's one responsibility that you must never delegate. You, and no one but you, must investigate whether an adviser is trustworthy and charges reasonable fees.

Never buy a stock because it has gone up or sell one because it has gone down.

Before you invest, you must ensure that you have realistically assessed your probability of being right and how you will react to the consequences of being wrong.

The true investor... will do better if he forgets about the stock market and pays attention to his dividend returns and to the operation results of his companies.

Undervaluations caused by neglect or prejudice may persist for an inconveniently long time, and the same applies to inflated prices caused by over-enthusiasm or artificial stimulants.

Mr. Market does not always price stocks the way an appraiser or a private buyer would value a business. Instead, when stocks are going up, he happily pays more than their objective value; and, when they are going down, he is desperate to dump them for less than their true worth.
