First of all, read the first two Market Wizards books. They contain all you need to know about markets, psychology, success, failure, and expectations of being a trader. Any other book(s) on "how to" or "how I made" are not worth reading at this point of your career. Trading is a game of experience; you have to earn your expertise more than any other profession because any rules that exist slowly mutate and change. And when you read too many trading books, you accumulate rules.
Secondly, there are an unbelievable amount of hedge funds out there and they basically all do the same thing, whether it's long/short, convertible bond arb, reversion to the mean, macro, forex only, or cash/future arb. They've all been created with the simultaneous explosion of liquidity thanks to the central banks of the world. However, the pool of tradeable securities has not kept up with this explosion, save for swaps and the odd batch from the CME, such as weather futures. So, they're all looking at the same thing and trade technical developments, rather than take positions with speculative conviction. The markets are too crowded.
Third, when you say a mutual fund can get you 10%, you are making the false assumption that because you are investing in said fund that it will give you 10%. The extra risk of a stock mutual fund has historically given a few percent above bonds, CD's, cash, etc. You are buying potential; it doesn't mean it will return 10% and frankly given the performance of the last 10 years, I believe they will not give you 10% in the next ten.
Fourth, the best part of a hedge fund is that you are running other people's money. The bad part is you have to put that money to work. You have to. And that can force you to take positions you really don't want. With your own money, you can choose not to trade for whatever reason. That is a big advantage. Plus, market participants won't try (and usually succeed) at guessing your position and push the market against you until you say uncle. That's how the CBOE option pits work. They all have the same information and basically figure out who's the weak hand and try to flush that trader out.
