Ted Williams wrote a book called "The Science of Hitting,"and in it he had a picture of himself at bat and the strike zone broken into, I think, 77 squares. And he said, if he waited for the pitch that was really in his sweet spot, he would bat 400 and if he had to swing at something on the lower corner, he would probably bat 235. And in investing, I‘m in a no-called strike business, which is the best business you can be in. I can look at a thousand different companies, and I don‘t have to be right on every one of them or even 50 of ‘em. So I can pick the ball I want to hit. And the trick in investing is just to sit there and watch pitch after pitch to go by and wait for the one right in your sweet spot. And the people that are yelling, "Swing, you bum"? Ignore ‘em. There‘s a temptation for people to act far too frequently in stocks, simply because they‘re so liquid. Over the years you develop a lot of filters, and I do know what I call my circle of competence, so I,I,I stay within that circle, and I don‘t worry about things that are outside that circle.
Defining what your game is, where you‘re going to have an edge is enormously important.
