Indian economic policy after independence was influenced by the colonial experience, which was seen as exploitative by Indian leaders exposed to British social democracy and the planned economy of the Soviet Union.[110] Domestic policy tended towards protectionism, with a strong emphasis on import substitution industrialisation, economic interventionism, a large government-run public sector, business regulation, and central planning,[118] while trade and foreign investment policies were relatively liberal.[119] Five-Year Plans of India resembled central planning in the Soviet Union. Steel, mining, machine tools, telecommunications, insurance, and power plants, among other industries, were effectively nationalised in the mid-1950s.[120]
The original version of Barbara Winter’s book, Making a Living Without a Job, came out in 1993, and in it, she recommended creating multiple "profit centers," as opposed to building a single income stream. Over ten years later,  Robert Allen, the real estate entrepreneur, also wrote a couple books promoting the idea of multiple streams of income. Back then, building more than one source of income was difficult, time-consuming, and expensive. Fortunately, things have changed today. The Internet has made it easier, faster, and more affordable to generate multiple income streams.
Question: You mention receiving $200k of passive income a year, but your chart shows half of that coming from real estate holdings, and reading between the lines it appears that you hold mortgages against those holdings. Then you conclude that $200k/yr of passive income should be enough to live comfortably anywhere in the world. So are you subtracting your real estate expenses (taxes, insurance, mortgage payments, maintenance, remote property management company fees, etc.) when you report your passive income from those properties? Really I think it’s the net (after taxes and everything) that tells us what is left over to “spend” on living, right? When I set up my spreadsheet to retire early at age 47, I calculated the after-tax income I would need to live. Then I compared that to my income streams (estimating tax on the taxable income streams) to measure the surplus/shortfall. Also some good advice from GoCurryCracker: If you can minimize your taxes so you’re in the 15% tax bracket, you can possibly receive tax-free long term capital gains. I agree with your philosophy that time is more important than money as we age. I am not sure I agree with a philosophy that is fixated on needing such a large income, and would rather minimize taxes if it’s all the same on the happiness meter. Furthermore, having 20 plus income sources in the name of diversification adds stress and requires more management (TIME!). I think this is fine for those of us while young, as we have the energy to work hard. But as time becomes more important, the extra headache of managing, planning, and buying/selling our assets becomes a resented hindrance on par with the resentment we felt when working for an employer and fighting traffic each day to go to a job we hated. Every thing we own in actuality owns us, by virtue of its demands on our time and affections, and that includes investments. It also includes our home, and is a good reason for downsizing. As long as we have food on our table, a roof over our heads, and clothes on our bodies, what more do we need? I think we need to consider freeing ourselves from the weight of the chains of managing too many ventures. Personally, I plan on investing in no more than 5 simultaneous ventures ever, with the exception of some IRAs that I just plan to let sit for the next 20 years (and therefore no thought or anxiety required).
ie first you need to haul ass and do something crazy, eg write a quality 20,000 word ebook (insanely not passive hahahah), but then you get to sit back and enjoy seeing PayPal sale messages pop up on your iPhone each morning as sale after sale after sale is made…on an ongoing basis and without any additional work. That’s some seriously Pina Colada flavored passive goodness!
An obvious example is over exposure to bank stocks, which have been excellent investments for over a century.  Though a foundation of most portfolios, bank stocks do involve more risk at certain stages of the economic cycle than many realise.  Being less exposed to bank shares in the last few months could have preserved some capital.  So, a more diversified approach can help mitigate some of these risks.
