This was by far my biggest return on investment. It took about two weeks to figure out how to format my book for paperback and get setup for Createspace, but this is nearly 70% of my revenue. It’s ironic because my e-book is $4.99 and my paperback is $14.99. I priced the paperback higher because I wanted to drive readers to the ebook, where I could update it more easily. What I learned, however, is that many of the people buying my book are parents, not students, and they are more familiar with paperbacks. There is also an incorrect perception that you need a Kindle to read Kindle ebooks.
Interesting post thanks. I have had similar thoughts about the passive income model – it’s not “passive income” at all, it’s just a different business model where you do the same amount of work to build a product/service and support clients in a slightly less direct way than standard freelance/project work. There are also greater risks with the passive income model – if you are simply selling your time as a freelancer or WordPress agency, you are guaranteed to be paid for your time. Whereas you can spend months or years developing a product, service or blog in the hopes of attaining “passive income”, only to find that it doesn’t take off and you never get paid for this time. In theory the gains of a passive income business are greater as it is scalable and the amount of work doesn’t necessarily increase as you get more sales, but the risks are greater too.
I think also a very good way to earn a nice passive income is investing in Cryptocurrency, especially in Masternode Cryptocurrencies, which provide a passive income in coins, also those carefully picked coins grow in value, so it’s a double gain! And a great coin to invest in at the moment is GINCOIN, which is the fuel for a really succesful project. Find more at GINCOIN Website: 😉
In addition to the obvious — increasing your monthly income — many people develop specific investment plans for their monthly residuals. Popular strategies include allocating monthly residuals to a retirement account, a down payment on a home, education expenses and an emergency fund. Your strategy should include establishing a reserve for income taxes if you receive residuals in full, without withheld taxes. This prevents unwelcome surprises at tax time.

I no longer count traditional publishing as passive income because after you’ve spent half a dozen years pitching agents, arguing with publishers, and having your heart broken repeatedly only to make about a dollar per book, it’s not really passive income. More like overdue income. The responsibility that traditionally published authors shoulder is much too high and the cut far too little to make this even a profitable, let alone passive, income option for most writers.

Also, I know from my personal experience that when you only do something because you think it’s a money-spinner you end up nearly killing yourself to get the idea over the line.  I remember creating a careers advice site that bored me to tears.  Every word I wrote, hurt a little.  All 200,000+ words!  Do not put yourself through this pain.  I know I won’t ever again.
