Teaching and tutoring English as a second language is a great way to make money online, not to mention open some doors for you to travel the world if you'd like. While full ESL (English as a Second Language) accreditation is recommended, as long as you’re a native speaker and have the ability to teach, there are people in countries such as Hong Kong or the UAE who are willing to pay upwards of $25/hr for you to tutor them English via Skype. Check out Indeed, Learn4Good and Remote.co for remote english tutoring jobs or sign up on a specialized site like VerbalPlanet or Chegg Tutors.
If you’re serious about making money selling things online, it’s pretty much impossible to not recommend Shopify. The platform gives you everything you need to get your online store up and running in less than a day including a custom domain, beautiful templates (so you don’t need design skills), secure payment options, and they can even take care of marketing and shipping for you. Whether you’re promoting your own products, designs, or curating other products for people in your niche, Shopify is the best option for powering your online store.
Make money on YouTube. People who love the spotlight and have other online hustles should consider creating their own YouTube channel. If you’re interested — and interesting — you can use the platform to market affiliate products, sell products you create yourself, or receive ad revenue for your informal tutorials or entertaining videos. Once you get the ball rolling, YouTube offers a partner program that can help you monetize your business further.
19. eBay – Of course you can’t read an article about making money online that doesn’t mention eBay. You can start an eBay store and get serious about it or you can just sell some stuff to declutter your home. Either way, I’ve made my fair share from selling on eBay and it’s still a popular way to earn money. If you decide to start an actual eBay store, you’ll want to find a drop-ship business like Doba that will store and ship items straight to your customers so you don’t have to deal with an inventory.
E-books represent about 20 percent of all book sales in the U.S. The good news is you don’t have to be a publisher with deep pockets to get in on the action. As a solo internet entrepreneur, you can sell ebooks directly from your own website. You can sell your own works or sell a public domain work. Simply upload it to your website (or seller account on Amazon) and start publicizing it on your social media platforms, on your email list, your blog, website, etc.
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.
My 10-year-old son brought home a book from our park’s free library box. It was a biology textbook – teachers edition. He said it looked interesting and hey, it was free (having no idea you could sell it). I scanned it in my Amazon seller app and realized it was worth around $150. He was so excited. We listed it for sale for $130 and it sold! Going to tell him, he just made $130!
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. 
Where Indeed excels at finding job postings across the web and acting as a search crawler for employment, maybe a full-fledged career is too big of a commitment at this point in your life. Elance is a site to find freelance work of all types. I’ve used it for quick writing, editing, copywriting, resume building, and other odd jobs and temp gigs. The experience has been great.
