The one thing I learned though from all those childhood experiences though is that you never can depend on one source of income. Eventually my mom caught on and stopped giving me all those extra bags of chips and I had to figure out a new way to make money. No matter how safe something seems there’s always the chance that you could lose that income and be stuck with nothing.

You can select any of the above-mentioned, based on your interest, skill, and capability to generate a second income source. However, these are just to name a few, there exists multiple ways to generate secondary income channel. You just need to identify the right one, which suits you the best. Remember there is no shortcut to success and you need to work hard to be successful and rich in the long run!
What I’m doing: I view passive income as funny money to keep myself sane during this long journey. I estimate 2-10 years to get to my goal depending on how active I am. The dollars created are just points one can accumulate. I’ve made passive income goals for each passive income type and check in at least once a year like I am now to make sure I’m on track. Passive income is also carefully managed to minimize tax liability. When you can build a buffer for a buffer, you are then free to take more risks.
There are a lot of article sites out there that share revenue, but my favorite (and it’s where I earn most of my article writing income) is InfoBarrel, which you’re very familiar with if you’ve been following my blog for awhile.  If you’re up for a very ambitious challenge, you can read about the one I wrote for earning $2,000+ per month with article writing.  The top InfoBarrel writers currently earn at least $2,000 per month.
One of the benefits of the time we live in is all the software and technology we have available. If you want to scale a business that’s bigger than yourself, you’re going to need systems in place to get you there. These systems should involve automating as much as you can. The less involvement of you in the day-to-day means you have time to focus on the big picture strategies that help your business grow. 
OK, I know what you're thinking — maybe you're not a writer. However, as Tamez says above, chances are, you're an expert sy ~something~. Also, chances are that other people want to know what you know. So whether you write an eBook on dating or tips on how to fix your car, once you write, self-publish the book, and let it go, it can sit on a site like Amazon and sell itself. Of course, you can market it, too, but that's another story! Some sites let you keep most of the earnings, while others do not.
You can find dividend stocks using Google Finance Stock Screener which is free to use. Set the search criteria for the P/E Ratio, and Dividend yield (shown as a percentage) criteria. You can set minimum and maximum values; in the dividend yield box, set it between 2 and 100. This will search for stocks that pay dividends worth between 2-100% of the current stock price.
The U.S. Internal Revenue Service categorizes income into three broad types, active income, passive income, and portfolio income.[1] It defines passive income as only coming from two sources: rental activity or "trade or business activities in which you do not materially participate."[2][3] Other financial and government institutions also recognize it as an income obtained as a result of capital growth or in relation to negative gearing. Passive income is usually taxable.

Overall income potential: Excellent – Although it’s very possible to make $0 with a niche site if it doesn’t receive traffic, you can also make a lot of money if you rank well for good keywords.  It’s not likely that you’ll make a living off one site, but they are generally easy to build.  If you can build one successfully, you can probably build several more.
Important measures were taken to address persistent Birr overvaluation, large external imbalances, foreign exchange shortages, and rising external debt. Inflation remained in single digits on average in FY2017, but accelerated to 15.6% by February 2018. Key challenges relate to limited competitiveness, an underdeveloped private sector, and political disruption. The lack of competitiveness constrains the development of manufacturing, the creation of jobs and the increase of exports. A larger and stronger private sector would seem to be the main response to strengthen Ethiopia’s trade competitiveness and resilience to shocks. The authorities are counting on the expansion of the private sector, especially through foreign investments in the industrial parks, to make Ethiopia’s growth momentum more sustainable. Political disruption associated with social unrest could also negatively impact growth through lower foreign direct investment (FDI), tourism, and exports.

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.

Coaching – I’ve been coaching ever since I was in college and I love it. And since I coach a club team, the time commitment averages only about 10 hours a week. The money isn’t great if you depend on it for living but it’s the perfect secondary source of income since it’s very easy for me to get hired as a coach(and it’s tax free through business deductions).
Article writing is one of those things that isn’t at all glamorous, and few people will get excited about it.  With that said, it’s one of the easiest ways to set up your passive income stream.  To give you some perspective, I wrote about 120 articles late last year and have hardly written any since then.  Since that time, my articles have earned me over $700.   I continue to earn $70-90/month without having to do any additional work, which is something I look forward to every month.

1) Save Like Nobody Owes You Anything. Passive income starts with savings. Without a healthy amount of savings, nothing works. Your overall “Money Strength” will be an F- if you do not build a financial nut. In our current low interest rate environment, you must save even more than before. It’s important to also realize that the savings I am referring to is AFTER-tax savings. You need to save money after contributing to your 401k and IRAs since you can’t touch pre-tax retirement accounts without a penalty until 59.5. Ideally everyone should max out their pre-tax retirement funds first, but if you don’t have enough funds and want to retire earlier then a decision to have more accessible post tax money will still work.
When you go shopping, do you use cash, your debit card, or a credit card? Instead, why not use a cash-back credit card and make money while you shop? It sounds contradictory, but Goudreau elaborates. "With a great cash-back card, you can make money when you spend money," she says. "The key is to keep your spending rates the same and pay your balance off in full at the end of every month. It's also important to pay your bill on time. That way, you're not paying interest or getting hit with any late fees, and any cash back you earn is pure profit.
Based on my initial experience of passive income, I feel real that real estate is best vehicle to build long-term investment. I live in Los Angeles and was able to cash flow my first rental property. What are you thoughts about starting out to build a passive income portfolio? I have utilized Lendingclub, online savings, and a small dividend/bond portfolio.
Example. Jean Blanc, a citizen and resident of Canada, is employed as a professional hockey player by a U.S. hockey club. Under Jean's contract, he received $150,000 for 242 days of play during the year. This includes days spent at pre-season training camp, days during the regular season, and playoff game days. Of the 242 days, 194 days were spent performing services in the United States and 48 days performing services in Canada. The amount of U.S. source income is $120,248 ((194 ÷ 242) × $150,000).
