Clayton M. Christensen

I helped start a ceramics company called CPS Technologies. We took it public in 1987 at $12 a share. Three months later, there was this horrible cliff: Black Monday. Fidelity had bought 15 percent of our stock, and their algorithm caused them to dump it all onto the market that day. We dropped from $12 to $2.

I didn't end up going bankrupt... I made some great investments and I held on to my money, which also enables me to have the freedom to do what I want now. But it's not about finances. No matter what, it's about keeping it real.

Having a Congress with a more diverse educational and professional background would serve the country well. And given the budget challenges facing America today, we might benefit from a few more cold, calculating problem solvers, and fewer courtroom impresarios.
