The number one idea is to view a stock as an ownership of the business and to judge the staying quality of the business in terms of its competitive advantage. Look for more value in terms of discounted future cash-flow than you are paying for. Move only when you have an advantage.

Avoid working directly under somebody you don't admire and don't want to be like.

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.

Once you get into debt, it’s hell to get out. Don’t let credit card debt carry over. You can’t get ahead paying eighteen percent.

Our success has come from the lack of oversight we've provided, and our success will continue to be from a lack of oversight. But if you're going to provide minimal oversight, you have to buy carefully. It's a different model from GE's. GE's works - it's just very different from ours.

The quality of the medical care delivered, including the pharmaceutical industry, has improved a lot. I don't think it's crazy for a rich country like the USto spend 15% of GDP on healthcare, and if it rose to 16-17%, it's not a big worry.

You don't have to have perfect wisdom to get very rich - just a bit better than average over a long period of time.
