Leonardo DiCaprio is set to produce and star in a movie about the collapse of Enron based on Kurt Eichenwald's book "Conspiracy of Fools." I plan to see it.

That title resonates with me because I was one of the many fools who bought Enron's bull, hook line and sinker. I liked the company. It seemed brash, daring and ready to change the world. For a reporter, Enron was a great story.

I spoke with Enron traders while reporting on the natural gas markets. I even met Jeffrey Skilling once or twice. He was tall, good-looking and wore a suit that I couldn't have afforded in my wildest dreams. Enron's headquarters in Houston was sleek and modern. The trading floor was buzzing with activity, at least when I was shown it during the tours run by Enron's PR staff.

Only years later did I realize that it was all a lie and I haven't been the same. As Eichenwald's book points out, Enron was a mess behind its shiny shell. Things were not nearly as great as I thought.

Whenever I hear someone say that investors need to "believe" in a company, I cringe. Yeah, investing is an act of faith, but it's not blind faith. You need to look very, very carefully before you leap.

The lesson of Enron is one that everyone's mother taught them long ago: if something is too good to be true, it probably is. Unfortunately, people seem to keep forgetting this and history continues to repeat itself.
