People don't realize that we cannot forecast the future. What we can do is have probabilities of what causes what, but that's as far as we go. And I've had a very successful career as a forecaster, starting in 1948 forward. The number of mistakes I have made are just awesome. There is no number large enough to account for that.
Getting into shape helped get me into a better mood, and when I'm in a better mood, I'm funnier. My general attitude is better.
