Get a new domain, preferably a .com, find a topic you enjoy or are knowledgeable about, and start writing about it. Your enthusiasm will (hopefully!) interest your visitors and make them want to return over and over.
Good content takes time to build, but pays dividends in the long run.
As abbeyvet said, Adsense isn't a way to get rich quick - except for the very lucky few. The rest of us put a lot of time and effort into our sites, and tend to be resentful of those who think they can buck the system.
Time + Effort = Rewards :) Good luck
I would advise you just the same. Probably now, it seems to you that your aim is unachievable and so distant, but once you start investing in your website in the right way, just as the person above says you will prove it right - time + effort are the keys to the rewards of your site.
