I downloaded this pdf several years ago and read through it again and again for great ideas. I do think some of the ideas, such as blogging to earn $, is a saturated area. More and more, you have to think of a unique approach that hasn’t already been done to death. But there are still some great suggestions on this list, so I recommend reading it thoroughly, then combing through the ones you like. Who knows what one will find if only one looks, eh?
Plus, it’s a great place for lots of other opportunities and ideas!
