 How can you replace your income with passive income so that you can quit your job forever? Now, all you have to do here is take your required monthly income and divide it by the value of that asset that you're going to be selling. So, in number one, I was selling iPhone apps. So, I sold that for $1.99. So, I'd have to divide 5k a month by $1.99. And I have to figure out, okay, I need about 2,500 customers a month. Now, if we can hit that target customer per month, we're free. We're done with the job, okay? We have our assets producing for us, and we spend our time actually building more assets. That is the digital landlord way. Create the assets, the assets bringing the money, you spend your time building more assets. So, over time, you have more and more assets that create more and more money. So, it's not that you're not working. We just call that passive income because you've already done the work, you've already created the asset, and you spend your time building more assets, and that's how you get a really, really high income over time.
