Money will not change how healthy you are or how many people love you.

Our policy is to concentrate holdings. We try to avoid buying a little of this or that when we are only lukewarm about the business or its price. When we are convinced as to attractiveness, we believe in buying worthwhile amounts.

We have long felt that the only value of stock forecasters is to make fortune-tellers look good.

Our system works. Over time, people will live better and better. We have a system that unleashes human potential, and now China has a system that unleashes human potential. We will have interruptions. We overshoot and undershoot sometimes, but your kids and grandkids will live better than you. Over time, we move ahead at a pretty damn rapid rate.

Investors should be skeptical of history-based models. Constructed by a nerdy-sounding priesthood using esoteric terms such as beta, gamma, sigma and the like, these models tend to look impressive. Too often, though, investors forget to examine the assumptions behind the models. Beware of geeks bearing formulas.

Does the business have favourable long term prospects?

Nothing sedates rationality like large doses of effortless money.
