If you really think you can beat the market, then you should join the VCs and you can make a bunch of money IF YOU ACTUALLY CAN ACTUALLY BEAT THE MARKET.

Once you make partner, you get your share in the returns and can make a lot more money since you will have way more capitol to invest than the spare change you have in your bank account.
