1. Using multiple streams of income I have had some income success.
Penny ads do work. Do not join a program that asks you for even a single cent of your own money. All of the operating money comes from the advertisers. Your part of it is to regulary read your portion of ads, but, more importantly get other readers to sign up under you.
I have made modest money with 3 different programs. All can be found here: http://wonway.biz/Welcome/?page_id=42
2. Retail online - Ebay, Amazon, Kijiji (now ebay owned), or better yet, find a product you like which is sold online and inquire as to whether there is an affiliate drop-ship program offered... if not, suggest setting one up with them!

3. Google Adsense - This works, but, like the penny ads, is but a steady drip in your multiple stream of income. With this program you will be creating web sites or blogging topics both of which you will be placing Adsense sponsored ads on. It is fun if you like site building and writing and there are plenty of free builders and ad sites to work with. http://wonway.biz/Welcome/?page_id=33
5. Employers like 'WEST ONLINE' and 'INFOCISION's online jobs are more conventional and may be more demanding than a 'free spirit' living full-time can stomach. But, it is an option. http://www.apply.westathome.com/index.html
