Hi Clean. I have yet to hit my payout on adsense. I took the first 13 months and focussed on writing -- researching, navigating through the site, learning about what markets/topics are good for traffic, socializing and so forth. My writing is good (so I'm told
) but it's a good thing I didn't quit my day job. 
If things settle at home this year, I will be focussing more on SEO and earning potential. I joined mainly for writing, not for making money. It's kinda the cherry on the top thing for me. I write all day and am paid for it. This is more of a hobby/interest thing for me. I love it for what it is.
