I think a very good system in a world with a lot of passive investors is one in which there are at least a few entrepreneurial investors, prepared to say what they think, prepared to propose a change in management, change in strategy, change in cost structure, capital structure.

I'm not emotional about investments. Investing is something where you have to be purely rational and not let emotion affect your decision making - just the facts.

I'm an extremely, extremely persistent person. Extremely. And when I believe I am right, and it is important, I will go to the end of the earth.
