A very thoughtful list here. Another relevant book published this year is “Retirement Planning for Young Physicians” by Dr. Ralph Crew. It covers many of the topics discussed here from the perspective of a physician who has successfully saved and retired. The book adds a lot to these discussions with a focus on the importance of lifestyle choices, as well as a realistic (though sobering) view of likely future physician income trends and how to plan accordingly for retirement.

Blogging is a fantastic residual income stream (don't mistake "residual" for "passive" -- in most cases you'll continue to work as your blog, and its income, grows). I won't go so far as to say it's the best residual income stream for freelance writers (informational products like e-books are fantastic for earning more in shorter periods of time for example), but they are one of the more consistent options once you build some stable traffic. And stability is a good thing. You don't always get a lot of it when you work as a freelance writer.
Amazon let’s you enroll in KDP Select when you’re publishing, which lets you give away the book for free on some days. Amazon markets the book heavily and the idea is to get people to try out your book and write reviews or to buy your other paid products. I did this in the beginning because that’s what I heard was effective, but it did nothing for me. I feel there are a few lessons learned:
Thank you for sharing your advice on Amazon and affiliate marketing. I just recently joined Amazon and have been updating my blogs using your techniques. Hopefully it works for me like it has worked for you, granted I know now based on your experience that I probably won’t see any big income from it for awhile but it is really nice to know I am on the right track to some success in the future.
Do you know of a successful business that needs capital for expansion? If so, you can become something of a small-time angel investor and provide that needed capital. But rather than offering a loan to a business owner, you instead take an equity position in the business. In this way, the business owner will handle the day-to-day operations, while you will act as a silent partner who also participates in the profits of the business.

Now I’ve been using Swagbucks for a while and have found the money works out to just under $2 an hour so this isn’t something that’s going to make you rich. You’d have to work 2,500 hours to make $5,000 so that’s about three and a half months, non-stop. The thing with Swagbucks though is you can do it when you’re doing something else so I flip through surveys and other stuff while I’m cooking dinner or flipping channels.
Thank you! This is really helpful. I have Amazon Affiliates, but I want to get more intentional with how I use it. The only negative thing I have about the program is that since I live outside of US the only way I can get paid is by amazon gift card, or expensive checks mailed to me. I mean, I can use the money I earn now on Amazon on things I actually need, but I don’t know if it’s worth putting a lot of effort into earning more when I can only use the money on Amazon 😛
Residual income will continue beyond a specified earnings horizon depending on the fortunes of the industry, as well as on the sustainability of a specific firm's competitive prospects over the longer term. The projected rate at which residual income is expected to fade over the life cycle of the firm is captured by a persistence factor, w, which is between zero and one.
It’s going to be a little bit tough in that I won’t be able to share the actual site here (to avoid an unfair advantage). I will say that the niche will revolve around PR writing — a specialty area for me, and one my research and experience has told me will probably monetize well (precisely the kind of thing anyone should know before starting a blog for income’s sake). I’ll hopefully find the domain name today to start the 3-month period now. I’m about to quit for lunch, so I’ll see what I can find during my lunch break and deal with the basic setup quickly.
So imagine this scenario: You get a brilliant idea for a mobile app you would like to make. You either need to know how to make it, or pay a programmer to do it instead. If you don’t have the cash, well good thing that you have a blog which earns you money through affiliate marketing commission, product reviews, as well as a the YouTube videos slowly piling up money from advertisement, and don't forget about the money from the online course and eBooks you sell.

Affiliate marketing spins around having readers click on the links in your articles and then subsequently purchasing the products you were writing about. Once they click the link in your article and then buy the product, you get a piece of the pie through commission. Commission varies among companies, but usually it is anywhere between 2% up to 10%.

This startup work is something that anyone involved in establishing passive income will admit requires some serious elbow grease. It’s the great exception to the whole notion of “passive” income in that it’s decidedly not passive. And for the most part, this is acceptable. People seem to get on board with this idea. “Hey, if I just buckle down and do a bunch of work right now, I’ll be able to sit back and enjoy the fruits of my labor later.” It’s a simple enough concept.
Investing in bonds: Similarly, bonds are an attractive way to engage in passive income. Over a recent 45-year period, bonds funds, as measured by Vanguard Funds, returned 7.1%. Of course, there's no guarantee that investments in stocks or bonds will always work out well, investing in them is by far the surest way to generate money through passive income.

Further, the clarified order awarded Karen sixty percent of the residual income that was earned from the income and commissions generated by the brokers within the first category, and after the date of divorce. However, the order also stated that Karen was not entitled to any of the residual income generated by the second or third category. Brad filed for a new trial, but the trial court denied it. He appealed, and the appeals court ultimately affirmed the trial court’s clarified order.

The Book on Rental Property Investing – Brandon Turner helps to run one of my favorite real estate investing sites, Biggerpockets. His book is written in the same easy style and with the same intent as the blog – to help everyone have an understanding of real estate investing. It contains lots of practical advice and it is completely honest in saying that real estate investing is not a get-rich-quick scheme… but anyone can do it.
Keep in mind that most passive income business ideas usually become largely profitable after a certain amount of time, depending on the time and money you put in. It is important to know that some, also, never make it and fail - just like any other business in the world. However, some passive income businesses are more vulnerable and others are less risky and more prone to giving a good payout at the end of the month.
PPS oh you thought I was done did you?!  The other parts of the book, although not truly passive income generation focused, are amazing too.  I know things like the low information diet and killing interruptions have made a huge difference to my success – and if I can try and get a little more consistency in my adherence to them, then happy freaking days!
