I don't think it makes any sense for an individual to invest in common stocks unless they know the company, work at the company, and so on.

Collectors become obsessive and then addicted. You become addicted to art and you can't live without it.

Unfortunately, the boards of art institutions tend to be populated with well-meaning supporters of the arts who often lack any business background or appetite for imposing appropriate discipline.

While I am proud of a number of accomplishments, there are real costs to being unreasonable. Long hours. Too little time with family. A near incapacity for, as they say, stopping and smelling the roses.

I have always believed that every great city in history needs a vibrant center.

In high school, I would drive my teachers batty. They would make a statement, and I would say, 'Why is that?' They didn't want to be questioned.

Frankly, I'm not sure how far I would get if I attended public school today. It's not just that public schools aren't producing the results we want - it's that we're not giving them what they need to help students achieve at high levels. K-12 education in the United States is deeply antiquated.
