Unless you're a freegan and have found a way to live entirely off the grid, you probably need some sort of steady income in order to survive. The traditional way to earn money, of course, is by having a job. You work for a company or start your own, and the work you do earns you money, which you spend on things like a mortgage, rent, food, clothing, utilities and entertainment.
Websites like Survey Junkie will pay you a decent chunk of change for the low-maintenance, borderline mindless task of completing surveys. Companies want to understand consumers better, and one way they do that is by compensating survey-takers (a.k.a. you). Most surveys pay between $0.50 and $1.25, and many of them take less than 5 minutes to do. You can read our full Survey Junkie review for more info.
