Well, you really, really need to change your entire outlook and work on the laziness.
But if you're not going to do that: Have you tried betting in prediction markets like Intrade? If you're good at noticing things that are "obviously" going to happen but aren't correctly priced, or have enough money to afford to be right on average, that could work. It does require an initial investment though.
I've been on it since August and have played conservatively so I've only made about a 5% return. (Made small amounts on the Chrysler and GM bankruptcies.)
Intrade is an interesting suggestion, but I don't think he could make enough on it. He wants 8000 USD a year, and even if we assume he can get 10%, he'll still need 80k invested.
I don't think he has 80k to spare, and I have to wonder - is 10% feasible in the long run? I could see getting it in an election year easily, because the markets are so volatile and heavily traded, but what about off-years?
