How it works: It’s a self-publishing website: You write a book and Amazon will help you get it published on Kindle.

Highlights: You’ll be a self-published author, and if everything goes right, theoretically you could make some good money. By everything going right, you’ll need people to presumably already follow you on social media and be interested in what you have to say. You'll get royalties, either 35% or 70%, depending what you choose. It sounds obvious that a 70% royalty is better, but there are various rules you’ll have to adhere to. For one, you’d have to price the book between $2.99 and $9.99. If you go with 35%, you can charge whatever you like. You’ll want to do some research on this before making a decision.

Drawbacks: Writing a book is hard, and if you really want to do it right, you may want to hire an editor or even a ghostwriter, both of which could set you back financially.
