If you have only a little capital and are young today, there are fewer opportunities than when I was young. Back then, we had just come out of a depression. Capitalism was a bad word. There had been abuses in the 1920s. A joke going around then was the guy who said, 'I bought stock for my old age and it worked - in six months, I feel like an old man!' "It's tougher for you, but that doesn't mean you won't do well - it just may take more time. But what the heck, you may live longer."

A lot of opportunities in life tend to last a short while, due to some temporary inefficiency... For each of us, really good investment opportunities aren't going to come along too often and won't last too long, so you've got to be ready to act and have a prepared mind.

A few major opportunities, clearly recognizable as such, will usually come to one who continuously searches and waits, with a curious mind, loving diagnosis involving multiple variables. And then all that is required is a willingness to bet heavily when the odds are extremely favorable, using resources available as a result of prudence and patience in the past.

It takes character to sit there with all that cash and do nothing. I didn't get to where I am by going after mediocre opportunities.

Opportunity cost is a huge filter in life. If you've got two suitors who are really eager to have you and one is way the hell better than the other, you do not have to spend much time with the other. And that's the way we filter out buying opportunities.

If you have the opportunities of Berkshire, an investment in gold is dumb.

We're guessing at our future opportunity cost. Warrenis guessing that he'll have the opportunity to put capital out at high rates of return, so he's not willing to put it out at less than 10% now. But if we knew interest rates would stay at 1%, we'd change. Our hurdles reflect our estimate of future opportunity costs.

"[Lawyers who file class-action securities suits] is not a group you would want to marry into your family. "That said, more than half the time the people being sued by the Lerach firm are guilty of outrageous conduct. The problem is, they don't mind (suing) the other half. They are an equal opportunity litigator."

Opportunity comes to the prepared mind.
