Donna's got great coverage of a WMW post that discusses the problems with the recent gain in notoriety of big AdSense earners (Shoemoney being foremost in my mind).

For two years, I did my time. I never did find a “real” job, and the two years I spent juggling bills and avoiding creditors was not fun. However, I also wasn’t sitting on my butt, watching soap operas all day. I wasn’t making much money, but I was learning HOW to make money, and I was working hard to achieve success.

Eventually, I branched out. I’d learned much more about SEO than I’d ever thought possible, and I began to take on clients. I also began creating websites that didn’t involve writing ColdFusion applications. At that point, I tried every idea that crossed my brain, and trust me, I had a LOT of ideas. The thought was that I’d throw all the ideas at the wall, and whichever ones “stuck” would be the keepers. The rest would die on the vine.

The trial and error system of growing AdSense earnings or growing a business overall is what makes web entrepreneurship such an exciting place to be. At SEOmoz, our business was not always smooth sailing and like Donna, we experienced exceptionally rough times (particularly after the dot-com crash), but we stuck to it, and today, we're able to give something back. I'm looking forward to having even more of that in the future.
