 So passive income source number two is software. This is that leverage we're talking about, those digital assets. So I learned this by developing iPhone apps. I'm not a developer. I've never coded anything in my entire life. So I'd hire it out just like building a house, just like you hire a contractor. We would develop those apps, we'd sell them in the app store. I'd get passive income every single day. And then I eventually sold those apps and got rid of them. Because I was sick of updating them every time there was an operating system update on the iPhone. But today I have software that is in your internet browser. So it doesn't need to be updated every time Apple decides to change something.
