When I was in college I played poker online and did well enough that it steered me towards an interest in trading on Wall Street. I liked what I learned about trading and decided that I wanted to someday start a hedge fund. My friend's father headed a public company at the time and he put me in touch with two fund managers so I could get some advice.
The first guy I called worked within an old-style bank. I don't remember much of anything from our conversation except that he seemed a bit... "traditional"? My questions weren't very good and his answers were pure vanilla. I learned nothing.
The second guy was a different story. He ran a nimble long/short fund with a few hundred million under management and had needed to scrap for every victory. From the second he picked up the phone I could tell he was short on time and low on patience. I kind of stammered through my list of questions and he gave me answers that appropriately reflected the poorly researched nature of my queries, which included things like "what is a long/short fund exactly?".
