The number one rule I give them is just not give them the golden rule. Do unto others, I'm not a religious guy, but, I mean, nobody said it any better in a couple thousand years than that, which may be why it's lasted to a certain degree too. I mean, more people are reading a 2000-year-old book about how to behave than anything that anybody's coming up with lately. Now it's got a lot of, particularly the Old Testament, it's got different kinds of stories, to some extent, but if the whole world lived by the golden rule, it would be such a more wonderful society.

I think motivation is the single most important factor in any sort of success. Physical fitness is important, technical skill is important, and maybe even the desire for money is important in some respects. But a sort of basic motivation, the desire to succeed, to stretch yourself to the utmost is the most important factor. Certainly in the field of exploration and activity, it’s the thing that makes the difference between someone who does really well and someone who doesn’t.

Not really. I thought that getting the Nobel Prize was a big interruption in my career, I thought and it was very distracting. It takes a lot of time you know, it just takes time to be honoured, you have to travel and you have to give speeches of things you have, oh it’s so often that you get bored to tears when you hear your own voice. And it’s really taking a lot of your time and there’s no way that during this time you can start something new, I mean you just profit from what you’ve done and there is no time to develop new ideas.

Question What bad recommendations do people in your field repeat too often? Craft & work
Most investors, of course, have not made the study of business prospects a priority in their lives. If wise, they will conclude that they do not know enough about specific businesses to predict their future earning power. I have good news for these non-professionals: The typical investor doesn't need this skill. ... The goal of the non-professional should not be to pick winners – neither he nor his "helpers" can do that – but should rather be to own a cross-section of businesses that in aggregate are bound to do well. A low-cost S&P 500 index fund will achieve this goal.

Question Which thinking habit do you wish you could break? Craft & work
Ironically, though, this is also the purchase in which I made my biggest mistake - of a kind, however, never recognized on financial statements. We paid $600 million in 1989 for Gillette preferred shares that were convertible into 48 million (split-adjusted) common shares. Taking an alternative route with the $600 million, I probably could have purchased 60 million shares of common from the company. The market on the common was then about $10.50, and given that this would have been a huge private placement carrying important restrictions, I probably could have bought the stock at a discount of at least 5%. I can't be sure about this, but it's likely that Gillette's management would have been just as happy to have Berkshire opt for common. But I was far too clever to do that.

Question What has life taught you about being human? Values & belief
Well, I won't say what I thought about them, particularly related to Bill Gates, but I would say it's astounding to me how human people are. I mean, it, here you had a guy that was a convicted guy, a sensational con man, and the percentage of people that he knocked off. I mean, whether it was, he found their weakness, it might have been sex. It might be power, it might be, whatever it might be.

Question Who makes your work possible behind the scenes? Craft & work
We have two pieces of regrettable news this year. First, Gladys Kaiser, my friend and assistant for twenty-five years, will give up the latter post after the 1993 annual meeting, though she will certainly remain my friend forever. Gladys and I have been a team, and though I knew her retirement was coming, it is still a jolt.
