Oprah Winfrey, as Maya Angelou and Tina Turner are no longer with us. These women are Afro-American queens who, despite growing up in the racist south experiencing physical, emotional and sexual abuse, rose to the top of their professions and are an inspiration to women everywhere.

Malala Yousafzai, Gloria Steinem, Meryl Streep – all suffragettes, in their own way.

And now, you've got nine countries, including, you know, a guy in North Korea. I mean, and there will be, something will happen. And we worried enormously about it when there were two. And we had perfectly, we had really pretty sane leaders in Kennedy and Khrushchev. You know, I mean, you were not dealing with unstable people or anything like that.

I go in every day to the office. I don't accomplish hardly anything. I mean, in terms of – it just takes me way longer to do things. And Greg is so good. It was kind of embarrassing how good he is, because he has covered – you know, we've got about 200 businesses within Berkshire, you know, that came about, and I can't name the manager's names or their wives names, or – and I haven't seen them, you know, in a long time. It's easier just to write the letter once a year and kind of do my own thing. Greg covers more ground in a day than I would in a week, even when I was at my peak, let alone my present condition.

Some material things make my life more enjoyable; many, however, would not. I like having an expensive private plane, but owning a half-dozen homes would be a burden. Too often, a vast collection of possessions ends up possessing its owner.

The asset I most value, aside from health, is interesting, diverse, and long-standing friends.

My first mistake, of course, was in buying control of Berkshire. Though I knew its business - textile manufacturing - to be unpromising, I was enticed to buy because the price looked cheap. Stock purchases of that kind had proved reasonably rewarding in my early years, though by the time Berkshire came along in 1965 I was becoming aware that the strategy was not ideal. If you buy a stock at a sufficiently low price, there will usually be some hiccup in the fortunes of the business that gives you a chance to unload at a decent profit, even though the long-term performance of the business may be terrible. I call this the "cigar butt" approach to investing. A cigar butt found on the street that has only one puff left in it may not offer much of a smoke, but the "bargain purchase" will make that puff all profit. Unless you are a liquidator, that kind of approach to buying businesses is foolish.

The reaction of my family and me to our extraordinary good fortune is not guilt, but rather gratitude. Were we to use more than 1% of my claim checks on ourselves, neither our happiness nor our well-being would be enhanced. In contrast, that remaining 99% can have a huge effect on the health and welfare of others.
