Great ideas here, and thanks for the link! I’m definitely interested in learning about using an Ebay store, although I’ve heard they are not as effective as they used to be. One interesting problem that arises though is with online work, that is, work performed via the internet. If one does not reside in one’s home country while doing it it might be considered illegal (so check on all those tax implications).

Andrew Rafal, Founder and President of Bayntree Wealth Advisors in Arizona, recently told me about his push to get clients to diversify their income streams. The Great Recession feels like an eternity ago now that the economy is looking up, he says. The job market is strong and consumer confidence is through the roof. As a result, it’s possible people are getting a little too comfortable.

1. The batting cage idea is very risky. I’ve seen many of them close over the years and it is not anything close to passive income if you want to keep the business going. You have to continually promote it and target youth leagues, coaches, schools etc to catch all of the new players who grow up and want to play. I’ve played at probably 8 batting cages over the years and 7 of them closed.
​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.

It’s outdated as far as referencing information contained within. It’s just detailed enough to make you feel like your getting some good information but in reality since the links don’t work your really getting nothing except some information that you then have to find detailed answers elsewhere, to bad they turned off their website with that supposed information. I also emailed the company for links for these detailed answers that they left me wondering and they never replied. I would pass on this book unless you want to get a general idea of some things to look at doing but they are not worth the read since they failed to uphold their website that had more information.
Another way to generate passive income is to invest and be a silent partner in a business. This is very risky, but with risk comes the potential for high returns. For example, several years ago both Lyft and Uber were looking for private investors to invest in their companies. Today, they are worth billions - but you as an investor would only reap that benefit if they go public via an IPO, or get acquired. So, it's risky.
Portfolio income can come from multiple sources – interest/bond coupons, stock dividends, financial strategies including derivatives and capital growth.  Each offers some cash flow and some also offer potential capital gain with some risk from liquidity and volatile prices.  In this low-yield environment, many investors rely too heavily on cash flows and to pursue this are venturing further into riskier areas than they’d normally consider.
