Abstract: If you are not so mature, you can take these jobs listed in http://www.usdsaving.com/series/101-Ways-to-Make-Money---Top-Ways-for-Teens/but if you believe you are mature enough, you can try the jobs as follows, they may be more suitable for you, making more for you, also.
1. Create Websites
You may not believe, but it is true that many people have asked me to build websites for them since I started this job several years ago. So if you do a little search and find small business owners, there is a lot of work available. As for small businesses owners, they also willing to pay these teens who might be great for this, because teens would be able to work for less than some higher-end website developers.
2. Blogging
I didn't believe before that blogging could make much money, but recently years I have found it did work out nicely. It isn't something that will provide income quickly, but if you stick to it, it can. And now I also try to make money from blog.
3. Become a Member of Focus Group
It is much likely to have focus groups in your area that may be willing to hire teens. Search "focus group" online to find where to start.
4. Design Web Logos
If you have a gift for design, it may be worth trying to make some money by designing logos for small business or blogs. You will be surprised for the incomes.
5. Freebie Trading
I first heard about freebie trading from a friend who earns much by doing it. But it seems to require a certain kind of person, but clearly there is potential as a decent money maker.
6. Offer to Take Census
The 2010 census is underway and there may still be census taker positions available in your area. But make sure you are 18 years old.
7. Start a Business on eBay
Half an year ago, I started a business on eBay to check whether there was money to be made since many of my friends asked me to make money from it. Although profit margins may be thin on eBay, there are over a million businesses on eBay, so it is a viable option and you do can make money in this way.
