There are lots of sites, but I use VIPKID. You just need a wifi connection, headphones, and a laptop with a good web camera to teach Chinese students English. They give you all the material you need to teach and an online portal, you just have to show up. The kids are super cute and fun to teach and I actually have a lot of fun doing it. Plus, I can set my own hours, work as much as I want, and take vacation whenever I want. It’s honestly great. And $20/hr goes a long way in Thailand. I make more than a lot of the English teachers I know who work in schools here. But, you have to be eligible to work in the U.S. or Canada to apply and you need a bachelor’s degree.
Matched Betting (not available in the USA) enables you to gamble (nearly) risk-free. I say nearly as there is always room for error! It involves placing bets on all outcomes of an event, using free online bets given out by the Bookies. Although it may take a while to get your head around the concept, Matched Betting can make a substantial addition to your monthly income.
Some of the best things in life are free and market researchers love to hand out new products in exchange for consumer feedback. If you like to try new products and have the opportunity to try them out for free, do some research and find the market research companies that offer products you desire to try. You can join campaigns and they will send the products or coupons to you to test them and provide feedback. You will generally have to fill out surveys and provide written reports based on your opinions. You will get to keep the products and they will sometimes even send you a monetary gift as an offer of thanks for doing the work.
