Though your answers must be honest and make sense, you don’t need to devote your full attention to online surveys – music to multitaskers’ ears. And you can invest as much or as little time as you like. Individual surveys can take anywhere from a couple of minutes to 20 or 30 minutes to complete, and you can do as many or as few as you want in one sitting.
Online focus groups are closely related to online surveys, and in some cases, the same companies administer them. Like in-person focus groups, online focus groups require more time and concentration than online surveys. Configurations vary, but you generally have to join a panel and engage on a certain number of issues per week or month. Online focus groups are often more selective than online surveys – if you don’t meet specific demographic or income criteria, you may not qualify.

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.
