Wall Street is a funny business. All you have is your reputation. Taint it and someone else will fill your shoes. Longevity comes from maintaining that reputation.

Successful hedge fund manager Andy Kessler looks back on his years as an analyst on Wall Street and offers this cautionary tale of the intoxicating forces loose in the world of finance that overwhelmed sober analysis.
