Create a killer course experience: With your course validated and in the works, you need to figure out how people will take it. Most course creators choose to host their courses from their own websites. This way, they get all the value of bringing customers back to their site on a regular basis. I host my own courses from a subdomain on my own site so I can easily add more. The course experience is incredibly important as well. And after trying most of the solutions, I highly recommend Teachable—an online platform designed specifically for courses.
Offer to watch children or pets. If you know anyone who has children or pets, you could easily begin a side gig as a babysitter or pet sitter. To let people know you’re interested, send out a group email describing your services, post an ad on Facebook, or tell friends and acquaintances about your availability in person or over the phone. You can also create a profile on a babysitting referral site like Care.com.
Even in the age of automation, some jobs still require a human touch. Companies often outsource those jobs via services like Amazon’s Mechanical Turk. These jobs can be tedious — tagging images, transcribing videos, classifying receipts — and can take anywhere from a few minutes to a few hours. Pay depends on the task, and the person requesting the work gets to approve the finished product before paying you. That can leave room for scams, so do your research and join a community like TurkNation, which can steer you away from shifty dealers. Read more about doing tasks on Mechanical Turk.
If you are a budding photographer and would like to be paid for your craft then you should consider setting up your own photography website. This is a great way to not only promote your services as a photographer but also to sell your images. You can charge visitors a fee to download your images. Or, if you’d rather, turn your site into a paid membership site, with free downloads of all images for paying subscribers.

In some cases, you may want to design your own products (we’re talking simple things, like t-shirts, magnets, mugs, etc.), but you don’t want to take on the cost of having inventory that you can’t sell. The below options are great for this situation – for the most part, it’s free to set up a virtual storefront, and you earn money when your products sell (and if nothing sells, it costs you nothing). These are generally great if you already have an established brand and want to sell your branded gear.
Find a profitable niche. Starting with your interests, write down as many niche ideas as you can. Think about topics people might search online. Ideas include passions (like surfing or body building), fears (like spiders or speaking in front of crowds) and problems (like getting out of debt). Do keyword research to see it others are interested in the topic. Find out if a domain name is available that matches the keyword 100 percent. 
The world becomes a better place when people learn new things, and if you are a good writer, you can put your skills to use and help educate the world.
