One thing I’ve realized is this: It’s FAR easier to work for an employer than it is to develop durable passive income streams for the average person. Why? Because working for an employer in a place that “needs” you means that it’s possible to show up and give a 50% effort. You can show up, put in your time, go home, have a beer, watch TV, and rinse and repeat all without REALLY having to put in the effort.
2. Treat Passive Income like a game, cheating is using your spouses income in this game. I understand some of the premise behind this, but I’m married, my wife has an income and we have a rental house that we consider ours. I’m not sure how I would count this since we also use another part of our own home(also rental income) to pay down the Rental house.
If you have a blog or other type of site, you can build affiliate links to different services on the website. Many people use Amazon as an affiliate partner. For example, if you are a beauty blogger writing about different products, you can set up Amazon affiliate links on your blog so that whenever someone buys the product you mention on Amazon, you receive a percentage of the sale. Amazon is not the only affiliate partner out there. Here is good, in-depth information on affiliate marketing. 
After employment, I think that most individuals gain income diversification through investing.  It is important to look at why we invest: because at some point we plan on using this money for something.  For most, it is saving for retirement, and the investing is done through vehicles, such as a 401(k) or IRA.  But investing is not just about stashing money away for a rainy day – that is what an emergency fund is for.  Investing is about having enough capital to generate income.
I think the holy grail of financial freedom is having so many passive income. This way you will never worry about your financial needs because everything is taken care of your assets. You will have all the your time in the world and visit all places you dream about. You have your time and money. This is the dream of most people which only few ever achieved.

The age old argument of total return versus income has been, incorrectly imo, categorized as an either or proposition. We are going to do both. Right now I have a lot cash in an on line money market. I also have investments in 2 passive Index funds in a taxable account. We then have substantial 401ks/IRA’s which we won’t touch for at least 10 years. My wife will continue to max out her sep and we will continue to invest in the index funds although with a smaller amount. We have already factored that in. I looked at how to cut into the monthly deficit. Here is what I observed.

Asset Managers often do better than the assets they manage. Eaton Vance (EV) and T. Rowe Price (TROW) also did exceedingly well over a 25 year period.
Capital growth in your portfolio can offset the eroding effect of inflation.  But any capital gains that exceed the overall inflationary effect can be drawn off to augment your portfolio income.  Of course, you must first generate those gains by making thoughtful investment selections.  While allowing strongly growing assets to keep doing that, it is prudent not to allow them to become a dangerously large part of your portfolio lest they go off the boil.  So if you selectively trim profitable positions along the way, you can boost your income.
