A number of operations have supported access to safe water sources and sanitation services, and the better management of water resources, including giving 4.2 million rural people an improved water supply (from 2013). A $250 million urban water supply and sanitation project is to increase the sustainable water supply and sanitation services in Addis Ababa and selected cities, providing one million people in urban areas with improved water sources, 2.7 million with improved water supply services, and 200,000 with sanitation services. A follow-on $445 million IDA credit was approved in March 2017.  Under its CPF, the Bank continues to support the government’s  goal of providing 100% national potable water supply coverage by 2020.
This is an interesting take and good advice for those who probably do not need to ever worry about becoming destitute. I’m sorry but too many of your options including your own list of income require quite a bit of initial investment/capital and these suggestions are useless to those living paycheck to paycheck. I’d like to see the average low to middle income household purchase additional property for rental, invest in their portfolio (if they can even start one), or even afford to have a vehicle or room to rent. Far too first world of a solution for the general public.
Unfortunately, it took a while for the real lessons to sink in. I was probably 20 or 21 when I read Rich Dad, Poor Dad the first time, which means I wasn’t exactly sure who I was yet. I knew I wanted to work hard and make money, but I wasn’t sure how. This made me a prime candidate for  multi-level marketing pitches, and the dream of “getting rich quick.”
I have only dabbled in drop-shipping before when I had an eCommerce platform 6 years ago or so. I think it is something that you could do on the side, but you would want to do in depth research on the industry you want to get into before setting up shop. It may be a little less passive up front, but over time you could take your hands off the wheel.
2) Find Out What You Are Good At. Everybody is good at something, be it investing, playing an instrument, playing a sport, communications, writing, art, dance and so forth. You should also list several things that interest you most. If you can combine your interest plus expertise, you should be able to monetize your skills. A tennis player can teach tennis for $65 an hour. A writer can pen her first novel. A finance buff can invest in stocks. A singer can record his first song. The more interests and skills you have, the higher chance you can create something that can provide passive income down the road.
The second category of passive income is drawing on sources that do not require capital to start, maintain, and grow. These are far better choices for those who want to start out on their own and build a fortune from nothing. They include assets you can create, such as a book, song, patent, trademark, Internet site, recurring commissions, or businesses that earn nearly infinite returns on equity such as a drop-ship e-commerce retailer that has little or no money tied up in operations but still turns a profit.
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.
I first discovered the power of passive income when I was a senior in high school. I started a mobile billboard business where I would rent a small piece of land from someone who had land along a busy highway. Then I would place one of my billboard trailers on the land and rent out the ad space on the billboard. I would usually charge about $300 per month for the ad space, meanwhile I was only paying $50 per month to the landowner for the ground rent. I got to the point to where I had 9 billboard faces and was making quite a substantial income for someone in high school. I really learned how passive income could free up my life… this business is what lead me into investing in real estate.
I think it’s funny how 1500 is the amount of extra income you mention because that’s what I’m shooting for! If I can make that much more each month to supplement my regular income, I will have almost all of my school debt payed off in one year! I’m really motivated. I use Mechanical Turk with Amazon to perform menial task and get a few extra bucks. I also use Varolo which is a fairly new idea. I really think it has potential. If you don’t mind me promoting it, here it goes.
The Indian rupee (₹) is the only legal tender in India, and is also accepted as legal tender in neighbouring Nepal and Bhutan, both of which peg their currency to that of the Indian rupee. The rupee is divided into 100 paisas. The highest-denomination banknote is the ₹2,000 note; the lowest-denomination coin in circulation is the 50 paise coin.[319] Since 30 June 2011, all denominations below 50 paise have ceased to be legal currency.[320][321] India's monetary system is managed by the Reserve Bank of India (RBI), the country's central bank.[322] Established on 1 April 1935 and nationalised in 1949, the RBI serves as the nation's monetary authority, regulator and supervisor of the monetary system, banker to the government, custodian of foreign exchange reserves, and as an issuer of currency. It is governed by a central board of directors, headed by a governor who is appointed by the Government of India.[323] The benchmark interest rates are set by the Monetary Policy Committee.
Another way to generate passive income is to invest and be a silent partner in a business. This is very risky, but with risk comes the potential for high returns. For example, several years ago both Lyft and Uber were looking for private investors to invest in their companies. Today, they are worth billions - but you as an investor would only reap that benefit if they go public via an IPO, or get acquired. So, it's risky.

Investor Income: This is the apex of income that one can achieve, you just have to live off your investments which you do not have to work much for once you have researched it thoroughly. Investors generate money by investing in other businesses, dividend paying equity shares, rental possessions, and other investments that need lesser amount of work. This work provides unlimited earning potential as they build their wealth as much faster rate than any other income categories.

I enjoy how you lay out real numbers. A lot of people wouldn’t do that. While you admit that you are somewhat conservative, I think the $1M in CD’s is just too conservative. Assuming you don’t need the cash flow now (which you say you just save anyways) then all that could be invested for potentially higher returns. For example, what if you bought San Francisco real estate along the way instead of CD’s. Or, an SP500 Index fund. I bet your average return would have been higher than 3.75%. Sure you could lose it, but the point is if you don’t need the cash flow now, you should try to increase that nut as high as possible until the day you actually need it. Your nut could be $5M right now if you had invested in asset classes other than CD’s for the last 14 years. Don’t get me wrong, you have done far better than me, but I guess I would take a little more risk if you don’t rely on that cash flow.

You must sacrifice the pleasures of today for the freedom you will earn tomorrow. In my 20s, I shared a studio with my best friend from high school and drove beater cars worth less than 10% of my annual gross income. I'd stay until after 7:30 p.m. at work in order to eat the free cafeteria food. International vacations were replaced with staycations since work already sent me overseas two to four times a year. Clothes were bought at thrift shops, of course.
It is hard to do both but you’re not supposed to. You’re supposed to get your safety net down THEN try to do high wire acrobatics above it – not set up the two at the same time. So get retirement and your emergency fund squared away, then consider the stock market (taxable) and real estate. There’s no rush! Don’t let others dictate your future because they don’t have the same priorities as you. 🙂
You may think of a savings account as just that, savings. But it’s actually another form of income as the money in the account will draw interest. And while this interest may be small, it’s still better than $0. Eventually, you can invest this money whenever an opportunity presents itself in order to gain other income streams.  Look into Tax Free Savings Accounts if you are going this route.
Most of us think of investment income as just the cash flow we get from bank interest, bonds, share dividends and property rents, some of which comes via a super pension.  But a more complete view is to also consider how growing the value of your investments can add to your spending potential.  This total return approach generates income from both income and growth to optimise spending from your portfolio across all market cycles, aligning cheap and expensive investments to your goals.
