Business Income: Contrasting to the self-employed ones, the business owners do not do all the work on themselves. In fact they get things done by different set of people working for them and they run the business. They create a system which then functions smoothly even with minimal supervision. This calls for a much less risky position and allows you time to build more and more income sources for yourselves.
Another great way to get started is to identify an area of interest you have. For instance, Robert Duff has been successful in building passive income by selling books on Amazon. Then, go out and start talking to people. Ask them, “What are you struggling with right now? What are your biggest pains? What’s something you wish existed that doesn’t?” That’ll give you some ideas about where to get started.
Active income is needed because you know you can always push away to bring in steady income. Passive income is needed to bring in a little extra on the side. You must ensure to never put all your eggs in one basket. When generating multiple streams of income, you must have different sources to rely on – because in the end, nothing is 100% reliable.
Thanks for writing this Mr. Samurai. I just got over the student loan hump but I feel pretty good about it at 27 having a graduate degree and being 100% debt free. Now that I’m on the other side it is good for my brain to absorb some of your knowledge regarding passive income investments. I love gleaning wisdom from older folks who have been there and done that. Mentors rock!

I just graduated college in May and was fortunate enough to secure an entry level consulting position that pays 55k/yr (a little less than ~35k after 401K, other benefits, and the lovely taxes that government bestows upon us). I started from “scratch” with my finances and have ~$2.3k in an online savings account. Since starting work a couple of weeks ago, I’ve had an aggressive savings plan (saving around ~40-50% of my monthly income). However, I’m going to become even more aggressive and live off 1 paycheck a month (and save the other paycheck) like you have suggested in many of your blog posts.

If the income is for personal services performed partly in the United States and partly outside the United States, you must make an accurate allocation of income for services performed in the United States. In most cases, other than certain fringe benefits, you make this allocation on a time basis. That is, U.S. source income is the amount that results from multiplying the total amount of pay by the fraction of days in which services were performed in the U.S. This fraction is determined by dividing the number of days services are performed in the United States by the total number of days of service for which the compensation is paid.
-The second brother has set up his stall in a very busy market place. It required some more starting investment but the returns were even more rewarding. On days like 31st December and 1st January, he easily earns 40,000 rupees. He is also very active on Facebook. Social media marketing helps a lot. Zomato rating of his stall is 3.9, and clearly, his focus on quality and customer satisfaction has paid off. Average monthly income is somewhere between 1 lac to 1.5 lac rupees.
India's gross domestic savings in 2006–07 as a percentage of GDP stood at a high 32.8%.[206] More than half of personal savings are invested in physical assets such as land, houses, cattle, and gold.[207] The government-owned public-sector banks hold over 75% of total assets of the banking industry, with the private and foreign banks holding 18.2% and 6.5% respectively.[208] Since liberalisation, the government has approved significant banking reforms. While some of these relate to nationalised banks – such as reforms encouraging mergers, reducing government interference and increasing profitability and competitiveness – other reforms have opened the banking and insurance sectors to private and foreign companies.[209][210]
Several economic historians have argued that real wage decline occurred in the early 19th century, or possibly beginning in the very late 18th century, largely as a result of British imperialism. Economic historian Prasannan Parthasarathi presented earnings data which showed real wages and living standards in 18th century Bengal and Mysore being higher than in Britain, which in turn had the highest living standards in Europe.[101][78] Mysore's average per-capita income was five times higher than subsistence level,[115] i.e. five times higher than $400 (1990 international dollars),[116] or $2,000 per capita. In comparison, the highest national per-capita incomes in 1820 were $1,838 for the Netherlands and $1,706 for Britain.[117] It has also been argued that India went through a period of deindustrialization in the latter half of the 18th century as an indirect outcome of the collapse of the Mughal Empire.[78]

California had a per capita income of $29,906 during the five-year period comprising years 2010 through 2014. About every third county and every third place in California had per capita incomes above the state average. Though somewhat counterintuitive, this implies that counties and places with per capita incomes even slightly exceeding that of the state can be classified as "high income" given the natural division of places into a top third (high), middle third (medium), and lower third (low) when ranked by per capita income. Hence, the upper third of all places in this ranking have a per capita income with a lower bound roughly equal to that of the state, about $30,000. The median place and county in California had a per capita income of roughly $25,000, and the lower third of both types of geographies had per capita incomes with an upper bound of about $20,000. Places and counties with the highest per capita income were concentrated in the San Francisco Bay Area, which has a relatively high cost of living. Those with the lowest per capita incomes were concentrated in the Central Valley, an economy in which agriculture assumes a primary role.
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.
