Sell photos. If you have a decent camera and a good sense of light, color, and composition, you can take and sell stock photos – i.e. nondescript images that lend themselves to many applications and are commonly used to illustrate online articles or products – with minimal effort. Stock photos of locations (a fire hydrant, a bare wall near an interesting tree, or anything you might find as a default background image on your computer) are easier to take, but stock photos of people (i.e. people arguing, people kissing, people laughing) usually sell for more, as they have more uses and require the written legal consent of your subjects. Hunt for a reputable stock photo dealer or database that will pay you fairly before signing on with anyone.
Drive for Uber or Lyft: If you're in a locale where you can find Uber or Lyft (or even one of the many competitors around the world such as China's Didi), you could easily make a respectable income. The hours are flexible and you can work as you see fit, making it perfect even if you currently have full-time employment but are looking to make some money on the side. 
In 2014, Caitlin Pyle made over $43,000 by working as a freelance proofreader…part time. When she wasn’t working, she even had time to go on several fun vacations. After she had a ton of success doing that, she decided she wanted to teach others how to do the same thing, so she started up Proofread Anywhere.

If you’ve got a way with words and expertise in a niche, there are plenty of sites that will pay for articles and content you write. Think of the sites you read regularly.

Ever since the idea of online auctions came into existence, the online selling market has been on the rise. Many are interested, but don’t know how to get started. There are still all kinds of ways to make money by selling online, whether you’re selling what you already have or buying and selling like a store. Before we get started, here are a few general tips when selling anything online:
Try Uber EATS or DoorDash. Uber EATS offers part-time work that’s similar to driving for Uber or Lyft. Instead of picking up passengers, however, you will pick up food orders and deliver them in your area. Pay works similarly, letting you earn a per-job rate plus tips. Door Dash works similarly, letting consumers order food from restaurants and connecting drivers to pick up and drop off their meals.
Here’s a good example of how lead sales can work in real life: My second website, Life Insurance by Jeff, brings in a ton of traffic from people who are searching the web to find answers to life insurance questions. While I used to have the website set up so I could sell these people life insurance myself, it was a lot of work to process all the different requests and clients. As a result, I started selling the leads I gathered instead.
