Not sure Im adding anything here:
About 6 years ago, I used to have loads of content-based websites, each was enlisted with Google Adsense. I was seriously good with
SEO, always in pursue of higher PageRank. But I constantly updating the contents. I did my day job, came home and spent all 3/4 evenings a week updating the contents of my sites, trawling the internet for resources and paying writers (namely from India) to provide contents for my sites. I got paid by Google around $2k every quarter, which wasnt bad for an evening job. But towards the end, I realised I didnt have any social life, affected my family life all for a some small change. Stopped doing it. Sold the sites on Digitalforums and Singingpigs etc. Made a bit of money. And move on to other stuffs like Sport Arbitrage and Sport Trading on Betfair....!
