"I'm a firm believer that to really understand a business takes years, not months. As an investment analyst you think you understand a business from the outside, but the reality is that, once you are inside, you can go on learning for five or ten years."

Freudian therapists do a lot of listening and very little persuading, and that was one of the reasons I eventually gave up being an analyst. You had to be too passive and not speak up, and you couldn't give homework to clients. While I was still an analyst, I wrote several articles criticizing psychoanalysis, but the analysts weren't listening to my objections. So I finally quit psychoanalysis after practicing it for six years.
