The stock of the greatest company in the world is crap if every investor already thinks it is the greatest company in the world. - Andy Kessler

The stock market teaches you the hard way - it's all in the margin.

But I was confused. Here we were scrambling around looking under rocks for great long-term investments, and every other hedge fund, or so it seemed, was doing some funny hedge of cheap yen money and T-bills. That's investing?

A product lowers the cost of doing something and eventually, customers will figure this out and buy the stuff in big volume, but they're not going to buy yet. You've got to have real conviction to step up and own this kind of company-you're staring over the edge of the waterfall, not sure when the growth is going to start.
