The truth is... YOU CAN MAKE MONEY ONLINE.
If you can post an ad on eBay - you can make money online. (My cousin just started buying a popular brand of microphones from a wholesale distributor in China for $32 and sells them on eBay for $85 like hot cakes!)
If you can post an ad on Craigslist - you can make money online. (Many offline businesses would be happy to pay you money to post ads on Craigslist for them or to generate leads for them via Craigslist. And there are plenty more ways to monetize Craigslist of course...)
If you can write a simple article - you can make money online. (You can either use the article to promote your own products, a product as an affiliate, or you can charge people to write articles for them!)
If you can post a thread in a forum - you can make money online. (There are millions of forums online in thousands of different niches that you can post links to your blog that has your affiliate offers on it.)
If you can blog - you can make money online. (There are people who just write about their everyday lives and/or their opinions while they sit back and collect advertising revenue from Google AdSense and affiliate commissions, etc.)
If you can invest a little bit of money to outsource a blog and a few articles - you can make money online. (This is a relatively easy route considering you don't have to perform any labor or spend time learning how to do certain things).
So, NO MORE EXCUSES!
Now go out there and make some money, or don't, but don't come around here saying that it's impossible to make money online because it's just not true!
