If you own a wonderful business...the best thing to do is keep it. All you're going to do is trade your wonderful business for a whole bunch of cash, which isn't as good as the business, and you got the problem of investing in other businesses, and you probably paid a tax in between. So my advice to anybody who owns a wonderful business is keep it.
We are growing the economy in smart ways and rebuilding our infrastructure and investing in science and development and that we stay true to those values that helped to get us here.
The best business returns are usually achieved by companies that are doing something quite similar today to what they were doing five or ten years ago.
The key to investing is not assessing how much an industry is going to affect society, or how much it will grow, but rather determining the competitive advantage of any given company and, above all, the durability of that advantage.
