But, you don't need to go further than that. You can simply write it and publish it and collect the income. That's all. Send out a couple emails to your list (if you have one) or post it on social media, and there you have it. Passive income. Now, the amount of income you receive depends on the quality of the book you've written. How well did you craft the message? How targeted was the information to your audience? It counts.

Thirst for income is likely to continue with interest rates expected to stay low, keeping government bond yields low for longer and their valuations unattractive.  Looking past bonds, the prices of high-dividend shares are historically high, which limits the likelihood that their dividends will rise markedly from here.  Striving too high for an income target tends to push your portfolio further out on the risk spectrum.
Real Estate: I currently own one rental property in San Francisco which I bought in 2003 (2/2 condo), one vacation rental in Squaw Valley, Lake Tahoe (2/2 condo), and my primary residence. Real estate is my favorite asset class to build wealth because it is easy to understand, tangible, provides utility, and rides the way of inflation. I recommend individuals try and get neutral inflation by buying their primary residence as young as possible. The power of inflation is just too hard to counteract.
What spurred this blog post was an idea put forth by my friend at ESI Money in which he talks about how the first million is the hardest. ESI shares how his net worth growth has accelerated. The first million took 19 years of work (the clock starts when he started working, not at birth!) but the 2nd million took just 4 years and 9 months. J Money took this same idea and started at $100k, which took him 7yrs 11mos. Each of the next $100k milestones took close to 18 months each to reach.
Income inequality refers to the extent to which income is distributed in an uneven manner. It can be measured by various methods, including the Lorenz curve and the Gini coefficient. Economists generally agree that certain amounts of inequality are necessary and desirable but that excessive inequality leads to efficiency problems and social injustice.[3]
And, let’s face it; not everyone wants to sling body wraps or nutrition shakes to their family and friends. That’s why offering a service is often one of the best, and least uncomfortable, ways to earn side income doing something you love. Maybe you want to clean houses or rake leaves or help people file their taxes. It’s totally up to you, and that’s the beauty of this option.
