It's got to be the best intellectual exercise out there. You're seeing through new situations every ten minutes. In the stock market you don't base your decisions on what the market is doing, but on what you think is rational. Bridge is about weighing gain/loss ratios. You're doing calculations all the time.
Warren BuffettIf you are not willing to own a stock for 10 years, do not even think about owning it for 10 minutes.
Warren BuffettI bought my first stock in 1942, in the summer of '42. I was 11 years old. And so 75 years have gone by. And I have never known what the market's going to do the next day. And that's not my game. My game is to decide whether I'm in the right economy, which America's definitely been ever since that time. The Dow has gone from 100 to 21,000 during that time. And no matter what the headlines say, or terrible things are happening - we were losing the war in the Pacific when I first bought stocks.
