You have to be intellectually honest with yourself and others. In my judgment, all great investors are seekers of truth.

Just as outright euphoria is often a sign of a market top, fear is for sure a sign of a market bottom. Time and time again, in every market cycle I have witnessed, the extremes of emotion always appear, even among experienced investors. When the world wants to buy only treasury bills, you can almost close your eys and get long stocks.

The balance between confidence and humility is best learned through extensive experience and mistakes.

A good trader has to have three things: a chronic inability to accept things at face value, to feel continuously unsettled, and to have humility.

The hardest thing over the years has been having the courage to go against the dominant wisdom of the time to have a view that is at variance with the present consensus and bet that view. The hard part is that the investor must measure himself not by his own perceptions of his performance, but by the objective measure of the market. The market has its own reality. In an immediate emotional sense the market is always right so if you take a variant point of view you will always be bombarded for some time by conventional wisdom as expressed by the market.

If you see a wonderful archaic Greek marble object in a museum, it's not only that it's beautiful, but what comes to your mind is the fact that it's 2,600 or so years old, and it was done by a human being at that time who you have such a limited ability to grasp - and yet you have this enormous ability to grasp.

Good investing is a peculiar balance between the conviction to follow your ideas and the flexibility to recognize when you have made a mistake.
