The best way to make money is to scam other people. There are a ton of scams out there, but the ones that work best tend to be the one that convince OTHER people that they can get something for nothing / doing very little work.

If you're artistic you could also look into doing graphic design, website design, etc., but believe me, it's very hard to get paid to do this even if you're good at it.

You could also try to sell a bunch of old crap you don't need on craigslist or eBay.
