I've learned mainly by reading myself. So I don't think I have any original ideas. Certainly, I talk about reading Graham. I've read Phil Fisher. So I've gotten a lot of my ideas from reading. You can learn a lot from other people. In fact, I think if you learn basically from other people, you don't have to get too many new ideas on your own. You can just apply the best of what you see.
Someone's sitting in the shade today because someone planted a tree a long time ago. The person sitting in the shade now should be grateful for the person who planted and tended that tree.

If you're extremely rich, and you have got children, my theory was, you give them enough so they can do anything, but not enough so they can do nothing.

This conservatism has penalized our results but it is the only behavior that leaves us comfortable, considering our fiduciary obligations to policyholders, depositors, lenders and the many equity holders who have committed unusually large portions of their net worth to our care.
The strategy we've adopted precludes our following standard diversification dogma. Many pundits would therefore say the strategy must be riskier than that employed by more conventional investors. We disagree. We believe that a policy of portfolio concentration may well decrease risk if it raises, as it should, both the intensity with which an investor thinks about a business and the comfort-level he must feel with its economic characteristics before buying into it.
It's a nightmare to administer some of this sort of thing, but I want to tell the shareholders of Berkshire, to the percent we own marketable securities or things for which there are market, even if those markets - I want to tell them what it's all about.
An irresistable footnote: in 1971, pension fund managers invested a record 122% of net funds available in equities - at full prices they couldn't buy enough of them. In 1974, after the bottom had fallen out, they committed a then record low of 21% to stocks.
