Use the law of supply and demand to your advantage. Most of us are familiar with the law of supply and demand--the more there is of something, the cheaper it is; conversely, the rarer the product or service, the more expensive it is. However, other than when we get to a toy store before sunrise to get on line for the latest fad toy that kids can't get enough of, we don't really apply the law of supply and demand to our own lives--particularly our careers. For example, if you're aspiring to do something that many, many other people want to do (so much so that they do it for free, as a hobby) then it will be far more challenging for you to make money doing it. On the other hand, if you do something that most people don't want to do, or if you get very good at doing something most people don't do all that well, then you can make a whole lot more money. In other words, choose a career in pharmacy over photography.
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.
