I think I naturally felt like I needed to pull back, and maybe that’s one of the reasons why I decided to get pregnant then because I was 37, and I had Lukas at 38. So I have not been covering combat recently. I haven’t covered combat in a few years. I’ve been in South Sudan. I’ve been under fire. But I’m not like — it’s a very different time, also, in history. … Now I feel like I was very torn about not being in Mosul, but I didn’t go because I felt like it was extremely dangerous, and I just couldn’t do that to my family.

On returning to Brisbane, I realised fairly quickly that I am an experimentalist at heart. A career as a diagnostic virologist was not for me!

But these days, if I have to choose between building my tennis résumé and building my family, I choose the latter.

Take no notice of anyone you don’t respect. […] Take no notice of anyone with a ­gender agenda. A lot of men still think that women lack imagination of the fiery kind.

Charlie and I decided long ago that in an investment lifetime it's just too hard to make hundreds of smart decisions. That judgment became ever more compelling as Berkshire's capital mushroomed and the universe of investments that could significantly affect our results shrank dramatically. Therefore, we adopted a strategy that required our being smart - and not too smart at that - only a very few times. Indeed, we'll now settle for one good idea a year. (Charlie says it's my turn.)

We've just passed a milestone: Twenty years ago, on January 3, 1972, Blue Chip Stamps (then an affiliate of Berkshire and later merged into it) bought control of See's Candy Shops, a West Coast manufacturer and retailer of boxed-chocolates. The nominal price that the sellers were asking - calculated on the 100% ownership we ultimately attained - was $40 million. But the company had $10 million of excess cash, and therefore the true offering price was $30 million. Charlie and I, not yet fully appreciative of the value of an economic franchise, looked at the company's mere $7 million of tangible net worth and said $25 million was as high as we would go (and we meant it). Fortunately, the sellers accepted our offer. The sales of trading stamps by Blue Chip thereafter declined from $102.5 million in 1972 to $1.2 million in 1991. But See's candy sales in the same period increased from $29 million to $196 million. Moreover, profits at See's grew even faster than sales, from $4.2 million pre-tax in 1972 to $42.4 million last year.

I think that Jay Powell in when, when the epidemic broke out, I think he acted in March of 2020 and I think if he'd waited two or three weeks, it would have been a disaster. Once the dominoes start toppling, they just start toppling and, and, and, and that line is shorter than anybody thinks, and it topples faster. And I think he did exactly the right thing, and he, he did it even stronger than Volker did. You know, I mean, he, he and Volker are my heroes at the Fed.

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.

In particular, my decision to sell McDonald's was a very big mistake. Overall, you would have been better off last year if I had regularly snuck off to the movies during market hours.

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.
