If you are unfortunate enough to find yourself no longer able to physically work in your chosen position, developing a skill set that will allow for a complete career change is a must. The passive income route as a second career is a great backup allowing you to hire out what you can’t physically do. Early on in my career I found I was unable to physically tolerate exposure to tobacco smoke. At that time, smoking was allowed in all offices, restaurants, etc. I was blindsided; who ever thought? It virtually removed me from most positions I had schooling for. As luck would have it, I had purchased a duplex while working and saved a small sum. When I had to leave my career, I made a down payment on another duplex doing any maintenance I could myself. If a physical setback of another sort should happen, I can hire.
Nobody gets early FI investing in bonds, CD’s, or even stocks unless they make a huge income or are extremely frugal or a combination of both. Paper assets just don’t provide enough returns. Business income can be great but it is typically not as semi-passive as I would like and there is a relatively high failure rate. That is if you can monetize an ideal to begin with. RE investing needs to be higher ranked IMO as a way that the “average guy” can become FI.
Income from the performance of services directly related to the use of a vessel or aircraft is treated as derived entirely from sources in the United States if the use begins and ends in the United States. This income is subject to nonresident alien withholding if it is not effectively connected with a U.S. trade or business. If the use of a vessel or aircraft either begins or ends in the United States, refer to Transportation Income in Publication 515, Withholding of Tax on Nonresident Aliens and Foreign Entities.

Purchasing a rental property is another common way that individual generate an income stream.  It is very similar to investing, in that you take a sum of money to purchase the property, and the property returns a cash flow – rent.  You do have expenses related to this that are different from investing, such as a mortgage, utilities, property taxes, etc, which all must be taken into consideration when calculating a return on rental property.
Industry accounts for 26% of GDP and employs 22% of the total workforce.[165] According to the World Bank, India's industrial manufacturing GDP output in 2015 was 6th largest in the world on current US dollar basis ($559 billion),[166] and 9th largest on inflation-adjusted constant 2005 US dollar basis ($197.1 billion).[167] The industrial sector underwent significant changes due to the 1991 economic reforms, which removed import restrictions, brought in foreign competition, led to the privatisation of certain government-owned public-sector industries, liberalised the foreign direct investment (FDI) regime,[168] improved infrastructure and led to an expansion in the production of fast-moving consumer goods.[169] Post-liberalisation, the Indian private sector was faced with increasing domestic and foreign competition, including the threat of cheaper Chinese imports. It has since handled the change by squeezing costs, revamping management, and relying on cheap labour and new technology. However, this has also reduced employment generation, even among smaller manufacturers who previously relied on labour-intensive processes.[170]
However, when you lack the money, you need time. You'll need to invest the upfront time now in order to reap the benefits of automatic income later. It just doesn't happen overnight. So don't expect it to. However, you can do this without quitting your day job. All it takes is some sincere effort over a consistent period, and voila! But, to get there, you'll need to consistently burn the midnight oil or get up at the crack of dawn. Your choice.
Audiobooks are witnessing a surge in popularity when compared to their text-based counterparts. If you have decided to write and publish an eBook, converting it into an audiobook requires little effort and is a great way to bolster your income. Amazon's Audible ACX platform connects authors with producers who can turn their written work into professional grade audio. Once that's done, the audiobooks are put up for sale on Audible and iTunes.
"For long-term savings, investing in low-cost index funds is the ultimate passive strategy," Goudreau says. "As legendary investor Warren Buffett recently told CNBC’s On the Money, 'Consistently buy an S&P 500 low-cost index fund. I think it's the thing that makes the most sense practically of all time.' By not picking individual stocks and, instead, buying a low-cost fund that tracks the market, you pay less in fees and take less of a risk. Then you can sit back and watch your money grow over time."

I also noticed that in your passive income chart at the bottom that you don’t include your internet income other than sales from your book. Is there a reason for that? Do you not consider is passive because you are actively blogging all the time to create it? Or do you just not want readers to know how much money you generate from blogging activities?
Within six months of selling, however, I had reinvested the proceeds from the home sale and brought total passive income for 2018 back up to an estimated $203,724. I'm not sure I would have sold the house without a clear plan for reinvesting the proceeds, since I'm bullish on the SF housing market long term. However, because I did have a plan, and the challenges of raising a newborn and dealing with rowdy tenants left me feeling a bit stretched, I decided to simplify and sell.

I wouldn't think of a high yield savings account as a source of passive income but your savings should be getting something (less like Seinfeld syndication residuals and more like a commercial jingle residuals!). It won't make you rich but it's nice if your baseline, risk-free rate of return on cash is 1% or more. The best high yield savings accounts (or money market accounts) offer higher interest rate and there is absolutely no risk. CIT Bank currently leads the pack with the highest interest rate.

I need to create a passive income stream that has a definable risk profile.I have $250k cash as a safety net in my savings account getting a measily 40 bps but I am somewhat ok with this as it is Not at risk or fluctuation (walk street is tougher nowadays). i have 270k in equity in my house, thinking of paying off the mortgage but probably does make sense since my rate is 3.125 on a 30 yr. I have 275k in my 401(k) and another 45k in a brokerage account that is invested in stocks that pay dividends.
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.
3. Start as soon as possible. Building a livable passive-income stream takes a tremendously long time, largely because of declining interest rates since the late 1980s. Gone are the days of making a 5%-plus return on a short-term CD or savings account. Today, the best 12-month CD is at 2.5%, and the best money-market rate is about 1.85%, which is not bad, considering such rates were below 0.5% just a couple of years ago. Know that every $100 you save can generate at least $2.5 in passive income.
There are a ton of ways to diversify your investments, some of which can send real income your way. By opening a brokerage account and investing in ETFs or mutual funds, you can earn real returns you can use to supplement your income. Of course, the flip side can also happen – as in, you can lose money. So, make sure you understand the risks before you dive in.
