17. Monetize a blog
Have you noticed how many food blogs there are now, how many home-decor blogs, how many knitting blogs? Tools, comics, math explanations, you name it, and there's a community of blogs for it. And each community continues to grow. You could start a blog and monetize it, meaning you join advertising and affiliate programs, sell ebooks, and add other features that allow money to flow toward you.
For example, you might sign up for Google Adsense and get paid each time someone clicks through on an ad on your site. Blogs can be about anything; the hardest part is getting a substantial following and enough traffic to generate income. Take a look at different blogs as many have posts on how the owners moved into full-time blogging.
Want a chance to use your wit or offer cool explanations of cooking and related phenomena? Want to simply promote your favorite product? See if that company has an opening for a social media manager that allows you to work remotely. You'd manage the company's social media postings; some positions might also have you troubleshoot or be the front-line customer service contact for people tweeting at the company, for example.
19. Sell your old stuff online
Got some old family items that you no longer want, like dishes or lamps? Sell them on sites like Etsy and eBay. Got a ton of old books? Sell them on Amazon as a third-party seller. Clothes? There are a bunch of used-clothing companies that will take shipments of your clothes and sell them on consignment.
20. Sell others’ old stuff online
If you don't have things of your own to sell, you can look through thrift stores and garage sales for items that you can fix up and sell. Be aware that this has become so popular that there is a lot of competition in some quarters when stores get new donations or shipments.
21. Be a website tester
Functionality is essential for all websites but especially for businesses who rely on their websites to get customers or make sales. You can try being a website tester who evaluates websites by trying them out and letting the customer know what you thought. Sometimes these involve conversations with the customer, while other times you'll fill out a questionnaire. You'll need fairly up-to-date computer access, but this can be a fast way to get a few dollars per site.
22. Cook or bake, and sell your creations
If your city has legalized selling home-baked goods from your own kitchen, you might look into that if you like to bake or don't mind making meals to go. Once you build up a reputation for safe, delicious food (and after you've gone through the city's inspection and permitting process), you could earn money in your own kitchen, selling meals and different foods.
Generally, people will come to your home to pick up the food, you'll deliver the food, or you'll run a mail-order business for non-perishable goods like cookies. You can sell on your own in your neighborhood, or you can join a site that matches people looking for food with your cooking.
23. Start subscriptions and support accounts
Related to monetizing your blog or social media is the path of starting subscriptions and support or donation accounts. A blogger might offer exclusive content for people who sign up for a subscription through the blog or through a site like Patreon. You might offer links that allow readers to donate money on sites like Ko-Fi. These should serve as additional income streams that show up occasionally; do not assume they will become regular sources of income.
