My very wise and politically savvy 17-year-old daughter says I get too emotional about political issues. I think she’s right. She knows that if she sees me race across a room, I have just read something about Trump. Turning ideas into feelings is the thing an essayist is supposed to do, but political punditry should probably be more detached.

Rushing to judgment. Looking for the bad in someone else before anything else.

My worst intellectual habit has to be overanalyzing everything. I do it all the time, because there are too many options in this world.

Wasting time reading blogs, magazines, newspapers. They have their place but they can become an addiction. And the real ways to gain understanding about issues are reading books and traveling.

The extraordinary delegation of authority now existing at Berkshire is the ideal antidote to bureaucracy. In an operating sense, Berkshire is not a giant company but rather a collection of large companies. At headquarters, we have never had a committee nor have we ever required our subsidiaries to submit budgets (though many use them as an important internal tool). We don't have a legal office nor departments that other companies take for granted: human relations, public relations, investor relations, strategy, acquisitions, you name it. We do, of course, have an active audit function; no sense being a damned fool.

Yeah and we get calls all the time, and there's so many calls, but the like I said, it takes me five seconds to say no. It takes, Greg's a little more polite than I am, but I just as soon get the calls just to see what people are doing. But they aren't offering anything that's at an attractive price, and what they want is a trade.

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.

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.

I've mentioned that we strongly prefer to use cash rather than Berkshire stock in acquisitions. A study of the record will tell you why: If you aggregate all of our stock-only mergers (excluding those we did with two affiliated companies, Diversified Retailing and Blue Chip Stamps), you will find that our shareholders are slightly worse off than they would have been had I not done the transactions. Though it hurts me to say it, when I've issued stock, I've cost you money.

Well, I ran out of gas. You know, I got to be what, 93 at that time, or something like that. And it just – same reason I gave up teaching. I teach – I was – I taught every year from when I was 21 till 88 or 89, and there just came a period when your body said different things to you, and you should turn it over to somebody, just like I did at Berkshire.
