P.S. I also fail to understand your fascination with real estate. Granted we’ve had some impressive spikes along the way, especially with once in a life time bubble we just went through. But over the long term (see Case Shiller real estate chart for last 100 years ) real estate tends to just track inflation. Why would you sacrifice stock market returns for a vehicle that historically hasn’t shown a real return?

​Self Publishing is mainstream today. When you purchase an eBook off of Amazon there’s a pretty good chance you’re buying a self-published book. Self-publishing is also ridiculously easy. I tried this a few years ago and couldn’t believe how simple the process was. To self-publish a book you’ll first need to write and edit it, create a cover, and then upload to a program such as Amazon’s Kindle Direct Publishing. Don’t expect instant success though. There will need to be a lot of upfront marketing before you can turn this into a passive income stream.

Those who can reap the benefits of residual income have typically put in an immense amount of effort and time in the beginning to be able to enjoy the rewards later on. Residual income, therefore, does not result in instant gratification. Those interested in earning residual income must have a lot of patience and determination to work as hard as necessary to achieve their ultimate goals of a long-standing income stream.
A perfect example of the Active Problem Solving + Automation concept is in my online courses I’ve created over the years, or my free webinars I’ve created more recently Each of my online courses and webinars are targeted to help people with specific problems, whether that’s in the area of affiliate marketing, podcasting, building a brand, and so forth. I am always improving upon the courses, but they are also evergreen for my audience.
You may not think of driving for Uber as a “passive” income strategy, and in many cases, it’s not. What you may not know, however, is that Uber has a feature called “Going my Way” that allows drivers to specify where they are headed and pick up passengers along the way. So why not sign up as an Uber driver and start getting paid for driving where you were already headed anyway?
Another great way to get started is to identify an area of interest you have. For instance, Robert Duff has been successful in building passive income by selling books on Amazon. Then, go out and start talking to people. Ask them, “What are you struggling with right now? What are your biggest pains? What’s something you wish existed that doesn’t?” That’ll give you some ideas about where to get started.

Perhaps a coworker purposefully tries to make your life miserable because they resent your success. Maybe you get passed over for a promotion and a raise because you weren’t vocal enough about your abilities, and mistakenly thought you worked in a meritocracy. Or maybe you have a new boss who decides to clean house and hire her own people. Whatever the case may be, you will eventually tire.

Companies use the return on investment, or ROI, ratio as a method to measure the rate of return of a company's capital investments. ROI gives companies a means to compare the effectiveness and profitability of any number of investments. Residual income measures the net income an investment earns beyond the lowest return on its operational assets. Each of these measurements enables company management to determine the profit potential of investments in capital improvement, proposed projects or potential acquisitions.
Buy a small business: A local small business, like a car wash or a laundromat, is a great way to put money down on a money-making venture. Automate it so you don't have to be on the premises unless you're collecting money. Go into a local business with your eyes wide open - study the books, especially on income and expenses, and examine water and utility bills if your venture will be open 24 hours.
One of the things I'm surprised your article doesn't mention is the tax advantages of this type of investment. The depreciation and rehab costs (purchasing distressed properties) can be huge deductions to ones income taxes, which none of the others have. Then, along with the appreciation of real estate, this passive income investment outperforms the notion of maxing out my 401k as well.
Many people talk about passive income and create the impression that you never have to do anything to keep that income going. The truth is that you will normally have to keep your eye on things if you want it to run smoothly. For example Richard Branson doesn’t run any of the 400+ companies he started but he goes over the numbers each day to make sure they’re performing well and calls the CEO if there are any problems.
