28. Subscription – If you think of something valuable (newsletter, online magazine, etc.) that you can consistently offer on a certain basis (weekly, monthly, etc.), you may want to offer a subscription service. This could be a fee charged each time your product is sent out or on a monthly basis. Either way, this has to be something that your customers can only get by subscribing to your website.
Start analyzing your decisions from the perspective of a firm. In economics, a firm's goal is simply to maximize profit. Well-run firms spend money only if they can expect to make more money from their investment, and they allocate their resources to the most profitable use. You're not a firm, of course, and you have other considerations, but if you make the majority of your time and money decisions by choosing the options that promise the highest return on investment, you'll likely earn more money, and that's good news for your shareholders (you and your family).
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.
