Nielsen (the same company that creates TV show ratings) has a research division that is similar to what survey companies do, which is gather information to help companies better market themselves to customers. Instead of having you take surveys, though, their computer and mobile panel is focused on gathering information pertaining to your “unique internet usage with people like you to build a picture of internet behavior.”
Considering that you have a finite amount of time, passive income should make up a large part of your work. If you're serious about generating any semblance of income online, then passive income should be one of your sole goals and ambitions. Why? Wouldn't you prefer to do the work one time and get paid repeatedly as opposed to relying on your time to generate that income? Invest the time at the front-end so that you can reap the benefits on the back-end. This means putting in a bit of sweat equity and not getting paid today. Rather, you'll get paid somewhere down the road. And you'll continue getting paid whether you keep building that passive income stream or you stop.
