Charlie and I decided long ago that in an investment lifetime, it's 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 now settle for one good idea a year.
If you don’t feel comfortable making a rough estimate of the asset’s future earnings, just forget it and move on. No one has the ability to evaluate every investment possibility. But omniscience isn’t necessary; you only need to understand the actions you undertake.
The truth is that I've got all my net worth safely in Berkshire and I will never sell a share so there is no one more concerned about what happens after my death than I am.
Mr. Market is kind of a drunken psycho. Some days he gets very enthused, some days he gets very depressed. And when he get really enthused you sell to him, and if he gets depressed, you buy from him. There's no moral taint attached to that.
Wild swings in share prices have more to do with the "lemming- like" behaviour of institutional investors than with the aggregate returns of the company they own.
We are trading away a little bit of our country all the time for this access consumption that we have over what we've produced. That is not good. I think it's terrible over time. But our country's productive grows enough so we actually can do that, and we'll still be better off. We just don't be as well off as if we hadn't done it.
