I agree that it is important to establish multiple sources of income, but I would be hesitant to group dividend stocks and real estate into the “multiple streams” bucket. Those are investments, and living off of investment income because you are in an emergency state is not a good plan. Cash flow from investments ebbs and flows more than the cash flow from a day job.

Here's an option that's still unfamiliar to many people but that has been growing in popularity: Lending money on a peer-to-peer basis. A major website for this is lendingclub.com, where investors have earned returns in the neighborhood of 4% or more annually. You'll be lending money to fellow individuals who have had trouble borrowing money through other avenues, and you can spread your dollars across many such folks to reduce the risk.
I am 30 years old and am retired. Previously, I made a modest salary as an Army officer. I own three duplexes and a quadplex in central Texas (10 rental units in all), and each of the properties provide me with net rental yields in excess of 15%. The last deal is actually an infinite return as my partner paid the down payment in return for a 50/50 split on a property that would otherwise provide a net rental yield of 18%. The above net rental yields also factor in an excellent property management team who manages my properties while I pursue other investment opportunities. To date, I have never interacted with any of my tenants nor have I ever had to personally deal with any maintenance issues.
It was easier recouping the lost $60,000 in rental-property income than I expected. For so long, my primary mindset for passive income was rental income. Having $815,000 less mortgage debt but still generating roughly the same amount of passive income with a much larger cash balance feels great. Further, my passive-income portfolio got even more passive, which is good as a stay-at-home dad to a newborn.

It covers Rental Income (Real Estate) or Interest Income (Bank Deposits). Though it is best suited for retirement planning but it can also act as second income during working years. Big question is how to fix the target for Second Income. Very simple, if your Monthly Expense is 50k & residential property can yield rent of 25k then you need 3 residential units i.e. one for self and two for second income source.

Remember, a successful business solves people’s problems. At first, you’re going to have to do the legwork and put in the time. But it’s about building something now so you can reap the benefits later, with the help of software, tools, automation, and people you hire. In this way, you can then turn this business that solves people’s problems into something that generates passive income for you!
However, until we get another reset in valuations (I’m calculating a 40% to 50% correction is justified ), I’ve moved largely to the sidelines. Beginning in July 2013, I began slowly reducing equity exposure and am now sitting firm at 40% with the balance in various forms of 5 yr cd’s and short duration bonds. This is down from over 60% when I ramped up to take advantage of the March 2009 lows.
But when so many turn down leasing one and one-half acre for one Wind Turbine for each 80 acres, that lease certainly does not materially affect the rest of the Farm or Ranch grazing pasture and the lease pays much more than the farm crow or grazing pasture lease, just because some lawyer said the lease was too long: 30 years plus 30 year option = 60 years, and the wind turbine company has selling production/electricity contracts for the next 150 years – which is needed to obtain financing!
Leveraging the internet to create, connect, and sell is something every creative person should attempt to do. The only risk is lost time and a wounded ego. You can start a site like mine for as little as $2.95 a month with Bluehost and go from there. They give you a free domain name for a year. Forget all the add-ons. Not a day goes by that I’m not grateful for my site.
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.

Today I sent my Annual Message to the Congress, as required by the Constitution. It has been my custom to deliver these Annual Messages in person, and they have been broadcast to the Nation. I intended to follow this same custom this year. But like a great many other people, I have had the "flu", and although I am practically recovered, my doctor simply would not let me leave the White House to go up to the Capitol. Only a few of the newspapers of the United States can print the Message in full, and I am anxious that the American people be given an opportunity to hear what I have recommended to the Congress for this very fateful year in our history — and the reasons for those recommendations. Here is what I said …[4]
Right now, I’ve got my day job, some index funds, a small income from my blog (about a penny a day so far – ha!), and some knitting patterns I designed and have for sale at various sites around the internet (not surprisingly, that doesn’t bring in much either). Eventually I’d like to write an ebook, although I have no idea what the topic would be yet. I’ll keep plugging away and hopefully it’ll become clearer in the future!
If you’ve ever thought to yourself, “I wish there was a product that did this,” then invent it! Create a product, medical or otherwise, and sell it as a company or get royalties for it. It’s not impossible to figure out, I have many friends who have taken a concept to market. Don’t overlook an invention as a fantastic means of attaining passive income.
Interest accrues daily and is credited monthly. Minimum opening deposit was $300 or a monthly direct deposit of $25. No minimum balance is required to obtain the stated APY. All fees and rates are subject to change after account opening. Annual Percentage Yield (APY) effective as of August 12, 2015 at 21:53 PM CST and is subject to change without prior notice. Unless exception applies, a 10% IRS early distribution penalty if withdrawn prior to age 59½ will apply. Fees may reduce earnings on the account. If you close your account prior to the crediting of interest, you will not receive the accrued interest. See fee disclosure and account agreement for details.
Do you want to earn $100, $1000 — or even more — on the side? You can start earning extra income today with the help of this list of ideas I’ve put together. Spend an hour or two each day working on items that are practical for you, and you can build alternative income sources to help you improve your financial situation  While many of the items on this list are passive income ideas, not all of them are. Some items require you to actively work for success.
But then figure out your unique selling proposition, what advantage you can offer that the market currently lacks. “My advantage in the passive income marketing space is that I’m not afraid to share my failures or where my income comes from,” says Flynn, who details his impressive income every month. “Transparency is huge,” he says. Referring to the personal bio on his LEED exam site, he says, “You might think I’m not benefitting from putting my story on there, but it helps me establish a relationship with people there. I’m someone who went through the same experience people went through on the site.”
I make some income from Retire by 40. Right now, all of the income is from advertising. If you’re curious about my online income, you can sign up for our monthly newsletter and see the break down. I’m not exactly sure how I would categorize my online income, though. If I stop blogging, the income will continue, but I’m sure it would decrease over time. I guess blogging income is 50% active and 50% passive at this point.
Distribution of family income - Gini index measures the degree of inequality in the distribution of family income in a country. The more nearly equal a country's income distribution, the lower its Gini index, e.g., a Scandinavian country with an index of 25. The more unequal a country's income distribution, the higher its Gini index, e.g., a Sub-Saharan country with an index of 50. If income were distributed with perfect equality the index would be zero; if income were distributed with perfect inequality, the index would be 100.

​Affiliate marketing is the practice of partnering with a company (becoming their affiliate) to receive a commission on a product. This method of generating income works the best for those with blogs and websites. Even then, it takes a long time to build up before it becomes passive. If you want to get started with affiliate marketing check out this great list of affiliate marketing programs.
An employee's main job location (principal place of work) is usually the place where the employee spends most of his or her working time. If there is no one place where most of the work time is spent, the main job location is the place where the work is centered, such as where the employee reports for work or is otherwise required to base his or her work.
