Today it happened, I finally reached milestone in Google AdSense lifetime revenue 100 EUR, what is equal to ~$137.54. 

It took me about 4 and half years :) Yes, I can hear your laughing. I first added AdSense to some of my site back in September 4, 2009.

Update: See how a year latter I cracked EUR 200 milestone with AdSense and how I finally cracked $40/mo with AdSense
