Here is a more concrete response to your request, which was for ways to make money.
There are many ways one can *earn* money. Making money will put you in prison, unless of course you work for the Federal Reserve.
As some noted above, find something you like to do and do it. Then, once you are good, find a way to make others want what you do.
Since that is pretty generic, here is something specific, but it is only a suggestion - a great one I think - so you will have to find another if this does not suit you.

Learn HTML5.
Practice HTML5. Do fun stuff for yourself and others. Do some free stuff for a baseball team or a neighbor’s yard sale, etc. Be creative and find ways to get some experience and reputation (via the free stuff above).
Once you feel good about it and others really like it, start selling it.
For example, yard sales. People have to advertise for those...spend money on an ad in the paper...spend money on signs, etc. You can create a yard sale template at 11yearoldjustwantstomakemoney.com (that is the domain you need to buy, or something shorter). For each yard sale, etc. just create a new internal domain, such as bobsyardsale.11yearoldjustwantstomakeoney.com.
Your template should have room for directions (google map link), dates, and maybe add pictures of some stuff. Then Bob can put a simple link in his paper ad or on the signs (this is where the shorter web address comes in).
You charge Bob $50, or $75 or $100, whatever, for the website and let him figure out how to let people know. Alternatively, you could find out how much it costs to put ads in the papers around where you live and add that to the price you charge Bob. $50 for website and $25 for ad in paper. You could add signs too - I am sure there is a local sign shop. If the sign shop charges $30 for the number of signs Bob wants, add that to the price, and you add a few bucks for yourself for getting the signs.
If you cannot mow lawns or shovel snow, create a local website to connect people who want their lawns mowed with kids/people who want to mow lawns. Charge the mowers/shovelers $10/month to list their name.
The point of my suggestion is, as others noted above, once you find something you like to do, can do it well, and can find people that want what you can do, money is no longer a problem.
