So as well as running the Niche Laboratory website I also have a day job. Right now I'm an English teacher overseas. You can read about my experiences on my new blog here. Effectively I'm getting paid for travelling. Isn't that the perfect dream job?
If you're a native English speaker (or even if you're not) then this could be a way that you make some decent money in 2018.
And don't forget that other languages are also popular with learners. Learners in Asia are particularly interested in learning Japanese, German and Spanish. It's a smaller niche than English. But then there are less teachers of these languages than there are English teachers. So they're still great niches!
If you have any comments or questions about making money by teaching English to other people, then post a reply in this thread.
More threads for you to read and post comments on.
