Like many, I was first really turned on to the idea of passive income by Tim Ferriss. In The Four Hour Work Week, he describes the system he developed with BrainQuicken, where the marketing, shipping, reordering, banking, and even customer service of the company was on complete auto-pilot. I found this idea intoxicating. The idea that Tim could travel the world learning to tango and staying on private islands while money just accumulated in his bank account seemed like some strange fiction — surely, this isn’t how people actually live, is it?
​Network marketing, or multi-level marketing, seems to be on the rise. Companies such as Young Living Oils, Avon, Pampered Chef, and AdvoCare are all multi-level marketing companies. You can earn passive income through network marketing by building a team underneath you (often referred to as a down line.) Once you have a large team you can earn commissions off of their sales without having to do much.

If you have specialized knowledge in a certain topic, you can put together an online course to teach others. For example, if you have experience in real estate investing, you can create an online course “Real Estate Investing 101”. The benefit of an online course is that once you create the course material, you can sell it to as many people as you want.
