I find myself constantly checking my google stats waiting for the profit spike. But then I think to myself. It should be my site i'm constantly checking/updating. What i'm trying to say is i'm wanting it to happen but i'm not making it happen by working hard with the SERPs and Content. Do you find yourself overwhelmed in Adsense?
Until you have a few hundred uniques a day, you'd make more money per hour panhandling on the corner... so why bother with advertising when you have no traffic? Get traffic... then worry about monetizing it.
I don't really have this problem. My problem is that once I start adding content to my sites, I have to force myself to stop. Luckily my 2-year old nephew stays with me in the daytime (what can I say, not having a job rules ) and he always manages to pull me away from the computer to play.
