Well,i will advice you to join those forums sites that are paying people to post on them.You can be making $20 per week.
I forgot to add, you can write squidoo lens and sell them on the squidoo forum. $10 per lens depending the quality of course.
$10 per month is very easy target. Even you can register in a freelancing site and do a small task and have this money. Also try fiverr, gigme5, microworker sites.
Blog about something you enjoy talking about. Then sell advertising on your blog. Ten dollars per month is really easy to get.
$10 a month is definitely not a hard target to meet. Fiverr seems like a good place for you if you have some kind of service to offer -- it doesn't have to be time-consuming and you can always outsource (it might take a bit out of your earnings if you outsource but if you repeat the method a few times, it should be easy to meet your target).
You can start selling Private Label Products like me! I have started to make some money and I am going to to expand it targeting for more profits.
$10 a month or even up to $100 a month is really easy. you can sell on fiverr, buy and sell on ebay or craigslist, you can flip domains
The best way --- create your own online business!!! I'd been struggling with making money online since a long time - tried everything from AdSense to Affiliate marketing stuff but could never make enough money from them, and just ended up being all frustrated. Then I researched people who were actually living the 4 hour work week style life and I happened to meet up with my mentor who actually taught me how to build a successful online freedom business from scratch. Here's my story on his blog to help promote his name in the blogging scene -- Success Story! Hope you take a look around and get the same value that I got from it
