This problem means that my income is down, but my mortgage still needs paying!
Yes, you could still make a living from it, but I wouldn't base a business model solely on AdSense unless I wanted to risk that mortgage payment yet again. I always sold my own advertising, plus augmented that with affiliate income, and added AdSense along to supplement my advertisers. When AdSense takes a dump, I still have a steady cash flow, just not as wide a diversity of advertisers as I solicit because I don't solicit.
BTW, if you're trying to pay the mortgage with AdSense, and looking for a mentor, you'll need to learn to sort out the real earners from the rest. Seek out publishers that actually make thousands a month and still bother posting, there are still a couple out there.
If you don't know how to spot real earners, I'll give you some hints. They typically don't participate in threads about daily fluctuations in income because they know it's going to be a bunch at the end of the month regardless of the periodic ups and downs. You also won't ever hear them use words like "glass ceiling" without a smiley face attached to the end of a sentence. They're also the publishers that tend to answer questions about the AdSense T&Cs because another reason they still have an AdSense account is they read them and actually abide by them, mainly because the mortgage is at risk. Real earners are typically too busy building and maintaining their sites, not complaining about AdSense.
In other words, just look for anyone being derisively calling a 'fanboy' and do whatever they're doing and you'll probably make some serious coin with AdSense.
The real key to AdSense is traffic, targeted traffic, traffic in a buying mood, and lots of it, from 1K-10K visitors a day for starters will usually generate some cash.
The best place to learn how to earn with AdSense is actually the Google SEO forum [webmasterworld.com] because if your SEO is done properly you tend to get better traffic and AdSense also tends to deliver better targeted ads.
