The interesting thing about it to me is the mindset. With all these "helpers" running around, they talk about doing deals. We talk about welcoming partners. The guy doing deals, he wants to do a deal and then unwind it in the near future. It's totally opposite for us. We like to build lasting relationships. I think our system will work better in the long term than flipping deals. I think there are so many of them [helpers] that they'll get in ea h other's way. I don't think they'll make enough money to meet their expectations, by flipping, flipping, flipping.

You need a different checklist and different mental models for different companies. I can never make it easy by saying, 'Here are three things.' You have to derive it yourself to ingrain it in your head for the rest of your life.

Rationality is not just something you do so that you can make more money, it is a binding principle. Rationality is a really good idea. You must avoid the nonsense that is conventional in one's own time. It requires developing systems of thought that improve your batting average over time.

Financial institutions make us nervous when they're trying to do well.

Harvard and Yale concentrated with venture capitalists that got the best calls and brainpower. Very few firms made most of the money, and they made it in just a few periods. Everyone else returned between mediocre and lousy. When returns happened, envy rippled through institutional money management. The amount invested in venture capital went up 10 times post-1999. That later money was lost very quickly. It will happen again. I don't know anyone who successfully resists this stuff. It becomes a new orthodoxy.

We tend to buy things - a lot of things - where we don't know exactly what will happen, but the outcome will be decent.

I believe in the discipline of mastering the best that other people have ever figured out. I don't believe in just sitting down and trying to dream it all up yourself. Nobody's that smart.
