Someone once told me I'm a sore winner, and they're right. I rarely take more than a moment to enjoy a success before I'm moving on and looking for the next challenge.

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.

Managers are responsible for setting workplace policies under which teachers can succeed. Managers are responsible for negotiating contracts that create the conditions under which teachers can succeed.

I am old enough to remember when America's K-12 public schools were the best in the world. I am a proud graduate of them, and I credit much of my success to what I learned in Detroit Public Schools and at Michigan State University.

A real collector does not sell.
