Monetize a hobby. While some hobbies actually cost money, others can be transformed into a profitable business venture. Ultimately, it depends on what your hobby is and how talented you are. You could turn your love of photography, for example, into a part-time gig taking family portraits and wedding photos or selling prints on Etsy or at arts fairs.
Great ideas although I find writing 20 articles in a day too exhausting. Similarly, I doubt if you can collect aluminum cans in one a day that you can sell for at least $100, unless you will do it with other friends and colleagues. This is a good idea for a fundraiser, though. On the other hand, I would recommend baby/dog sitting or house/yard cleaning.
Along the same lines as trivia, you can get paid for just using your mobile phone and allowing companies to know what you're doing on it. For example, Nielson Mobile Panel is an app that you can earn rewards on just for having it installed. It will take snapshots of what you're doing and use those for advertisers to know more about your demographic. It takes away some privacy, but you get paid for it.
The cash back industry is ruthlessly competitive, isn’t it!? All these apps want new users, which means you can load up on welcome bonuses. The Ibotta app is another opportunity to get a bonus: they are giving people $10 when they sign up. Unlike the other apps mentioned in this article, Ibotta specializes in getting you cash back at grocery stores.
Make and sell crafts. If you are even a little bit crafty, consider selling your goods on a site like Etsy. Though you can make more money on intricate projects (ex. an exquisitely woodburned gourd), even labor-light projects can bring in good money if you’re willing to produce them in high quantities. Who knows – if you do well, you might even be inspired to start a crafts business.
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.
