The other point is that it is pretty easy to get started.  You don’t need to be super rich, and you don’t need a lot of time to get started.  To say it requires no time would be a lie, but you don’t need to make anything listed above your life.  You can work at your job, invest your excess income, save to buy a rental property or rent out a room in your current house, and you start a side job online without breaking a sweat.

Investing in a business: Another good way to generate passive income is to invest in a business --even a small one -- in return for a percentage of the profits - just like Shark Tank, only smaller. Lending $10,000 to a local business that, for example, is working on a mobile app for Apple phones could lead to a passive income-generated share of the profits when that mobile app starts selling like hot cakes.
Sam…just read this article and I want to say that this is the best posting on passive income I have ever read…in a blog, article, or book. Thanks for making a difference and being an inspiration as to how it can all be accomplished. One of the great benefits of the internet is that people are willing to share their stories and experiences with each other online. If we had this when I was working professionally (20-40 years ago), it would have saved me from making some rather poor financial decisions that affected my retirement income. In a way, the internet is making up for the loss of financial security in the loss of The Defined Benefit Plan for retirement. Bravo!

This was a very inspirational article! I too spent 20+ years in a high-stress career selling a high-end product under a 100 percent commission plan; that is, no salary! I realized, after racking up millions of frequent flyer miles, that there had to be a better and less-stressful way of making a living. My goal was to design my own lifestyle free of corporate shackles, which required a pre-determined amount of passive income.
Retirees are paying a high price as the world stimulates its way out of the GFC (Great Recession).  After a 30-year bull market to the lowest interest rates the world has ever seen, bonds have become highly priced and now don’t generate enough to meet income needs.  Just 5 years ago the average income from $100,000 invested in a 10 year Australian Government Bond (10yrs) was $5,600 p.a.  – now it’s less than half at $2,600 p.a.
