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.
Buy underpriced used books. Outfit a phone with an ISBN reading app, scan the ISBN numbers of books at used bookstores and thrift shops, and compare the asking prices with what the books are selling for on a site like Amazon. Whenever you get a good hit (which won’t be often but, since the process is fast, won’t take long, either), buy the book and resell it online. Be discreet about this, as the store managers probably won’t like what you’re doing.
If your goal is to make enough money to retire early, prioritize earning potential over job satisfaction, since you plan on getting out of the rat race early, anyway. Consider the types of jobs that pay extraordinarily well in exchange for hard work, little psychological satisfaction, and a punishing lifestyle, such as investment banking, sales, and engineering. If you can keep your expenses low and do this for about 10 years, you can save a nest egg for a modest but youthful retirement, or to supplement your income while you do something you really love doing but doesn't pay much. But keep in mind that delayed gratification requires clear goal-setting and strong willpower.
Here's a far easier way to receive passive income: Use cash-back or rewards credit cards. (If you're carrying a lot of debt or don't have the discipline to use credit cards responsibly, you're best off not using this income-generation method.) You can collect flat-rate cash-back percentages up to about 2% with lots of cards, while some cards offer more focused rewards or cash back based on certain kinds of spending or certain retailers.
Creating a jobs board website can be another profitable venture. The ‘jobs’ field can be quite saturated, so it is important to find a niche that is still crying out for a jobs board website. Monetize this type of site by charging businesses to list their jobs on your site. Those searching for jobs could also be charged a fee to access the higher paying job adverts.
18. CraigsList – Some things don’t ship very well. Other things may make you feel uncomfortable to sell to someone across the country. Anytime you’re selling a large item or something you just don’t want to ship, Craigslist is a great place to go. It’s simple to list your item (again, take good pictures!). If you don’t like the idea of putting your phone number out there, the interested individual can send you a message to your inbox without even getting your email address.
Using a food delivery service can’t necessarily earn you money, but it can help you save you money if you constantly find yourself throwing out half the food you buy. Food delivery services send a box of food every week with new, sometimes unique vegetables, meat, fruit, and so on. If you don’t have time to shop and want simple meal-prep that leads to a good meal, a food subscription service may be perfect for you.
