To make money on AdSense you should follow this awesome strategy "Successful Site in 12 Months with Google Alone". Yes it's hard but making money isn't easy, the main way to be profitable with AdSense is to give profits (value) to your website's visitors!
Nice work soul_of_god!! If you would be so kind as to impart you wisdom on us and at least let us know how many websites you have running to make such a great living, any guidance even vague would be inspiring. Thanks!
the one interesting point is that non of these guys (apart from Shoemoney) set out to make money from online advertising, they created quality sites and the adsense revenue was a secondry addition.
