Of course I'm troubled by huge consumer debt levels - we've pushed consumer credit very hard in the US. Eventually, if it keeps growing, it will stop growing. As Herb Stein said, "If something cannot go on forever, it will stop." When it stops, it may be unpleasant. Other than Herb Stein's quote, I have no comment. But the things that trouble you are troubling me.

We have a high moral responsibility to be rational

See's candy company was the first high-quality business we ever bought.

We have found in a long life that one competitor is frequently enough to ruin a business.

What's fascinating . . .is that you could now have a business that might have been selling for $10 billion where the business itself could probably not have borrowed even $100 million. But the owners of that business, because its public, could borrow many billions of dollars on their little pieces of paper- because they had these market valuations. But as a private business, the company itself couldn't borrow even 1/20th of what the individuals could borrow.

Forgetting your mistakes is a terrible error if you are trying to improve your cognition.

All sensible investing is value investing
