Make Money On Line for Real -----80/20 rule

Have you ever heard in business that 80% of your income will come from 20% of your clients????
This probably applies to the blogging business as well.
I am finding Google to be the biggest player.There will be few things other than that that will bring in income....for me maybe the 20% will be ttz media and ad auctions.
And this site unlike most of the others will tell you what doesn't work so you can concentrate on what DOES work!!!
Also further to my Forex post ..can you imagine they offer a small account of 250 or 300 dollars!!!That would last about one day on there!!!!
I imagine you would need $1,000,000 to really trade.
