For me, I'm still looking for that method after about 2 months. I tried bum marketing, made a few hundred, but I don't like writing articles much. I also tried building a small adsense site, made about 15$ with a few articles (still going up everyday), but the best way to drive traffic to an adsense site is with articles, so I guess it's not for me.
So I haven't found it yet. Not sure what method I should try next. It's a bit annoying at that stage, because you're tempted to buy every WSO out there lol.
