The internet is a gold mine if you know how to access that treasure. You'll hear many stories of people making a lot of money from just sitting at their computer, and it is entirely possible. I know of many folks making six figures a year from just working online.
Unfortunately many money schemes can be scam so it's important to do your research. The infographic below shows over 200 ways in which to make money online. Every one is completely legal and are pretty straight forward.
When it comes to making money online you just have to be willing to learn and take out the time to do it. Instead of sitting on the couch watching your crappy TV shows, you could easily sit at your computer and make money.
Even if you're not willing to give up your full time job, you can easily fit these tasks around it. It's a good way to bring in a few hundred every month and add it to your income.
I myself make money from the following ways listed in the infographic - writing/blogging (like this article I'm writing now), graphic design, coding, internet marketing, freelancing, affiliate marketing and advertising. It is a lot and that is because it's my full time job. If you do this sort of thing full time, you can easily carry out many different ways to make money. And they all add up at the end of the month.
