The one thing I will tell you is the worst investment you can have is cash. Everybody is talking about cash being king and all that sort of thing. Most of you don’t look like you are overburdened with cash anyway. Cash is going to become worth less over time. But good businesses are going to become worth more over time. And you don’t want to pay too much for them so you have to have some discipline about what you pay. But the thing to do is find a good business and stick with it.
