Making money whit adsense

[Snide]

Would you say that its possible to make money whit adsense?

At the moment i have 1 major site ( 3 years old 2k posts, no niche, updated daily, PR 2) and a bunch of minor sites. But i dont get much clicks, its about 15 clicks a month, which gives me a few bucks. Been doing adsense for 1-2 years now and havent gotten a payout yet.

So what could be the solution here, make posts whit higher CPC? Set up more sites and rank them higher? Change ad placements?

I do belive that i am doing something right when i can get one click every second day, but i want to do it better and get a bit higher CPC.
