Quotes from the same author
The ability to change one's mind is probably a key characteristic of the successful investor. Dogmatic and rigid personalities rarely, if ever, succeed in the markets. The markets are a dynamic process, and sustained investment success requires the ability to modify and even change strategies as markets evolve.

If you don’t stay with your winners, you are not going to be able to pay for the losers.

One of my favorite patterns is the tendency for the markets to move from relative lows to relative highs and vice versa every two to four days. This pattern is a function of human behavior. It takes several days of a market rallying before it looks really good. That’s when everyone wants to buy it, and that’s the time when the professionals, like myself, are selling. Conversely, when the market has been down for a few days, and everyone is bearish, that’s the time I like to be buying.
