Well, my adsense daily earnings followed suit. There were years I didn't make up to $20. And now I making that in a week! I wouldn't have imagined that 4 months ago. And the best part of this whole surprise is that I didn't do anything differently. In fact, I do not think I did anything at all.
But I like the effect it's having on me. I now blog more and daily too. I no longer have a frown across my face when I check by blog statistics or adsense earning. I only hope it lasts.
