It might sound a bit hard to believe, but you can get paid to surf the internet. If you install a company's software, they will often pay you to keep it on while you are surfing the web. The reason the companies do this is so that they can track your activity and figure out what sites their users go to, as well as figure out how to market. The downside of this one is that sometimes you'll start finding random advertisements popping up, so do your due diligence and get a popup blocker (can be found for free by running a Google search).
