Pillars for creating wealth - What have you "created"?

[Tyler McGill]

Hello everyone,

I, like so many before me, and like many of you, am on the track to build personal wealth and at a minimum achieve financial independence.  I discovered BP around 6 years ago when I happened to sit in on a presentation Scott Trench gave at my school about how to go about building wealth after we graduated.

Fast forward about 4 years,  I bought the audiobook of Set for Life, which is one of my favorite books to recommend to anyone who is serious about FI.  In the book, Scott talks about four pillars of wealth building: save, earn, invest, and create.  I wanted to create a thread where people can discuss and exchange their ideas on the "create" part.

When I think of creating in this context, I think of something that provides royalties, like making music or writing books vise a business that would fall into the earn or invest pillars. 

If you've managed to "create" something that earns you passive income, what did you do?
