Thanks for the great article…although I have to point out many of the items listed are not passive but active, such as selling bodily fluids, writing blogs or resumes, and collecting bottles and cans. To be truly passive, the income source must require no effort on your part (after initial setup). Real estate, dividends, P2P lending…these are truly passive income sources.
In early modern Europe, there was significant demand for products from Mughal India, particularly cotton textiles, as well as goods such as spices, peppers, indigo, silks, and saltpeter (for use in munitions).[71] European fashion, for example, became increasingly dependent on Mughal Indian textiles and silks. From the late 17th century to the early 18th century, Mughal India accounted for 95% of British imports from Asia, and the Bengal Subah province alone accounted for 40% of Dutch imports from Asia.[81] In contrast, there was very little demand for European goods in Mughal India, which was largely self-sufficient.[71] Indian goods, especially those from Bengal, were also exported in large quantities to other Asian markets, such as Indonesia and Japan.[82] At the time, Mughal Bengal was the most important center of cotton textile production[83] and shipbuilding.[84]
Hi, I’m an 18yr old who is about to enter college with a substantial amount of federal aid and scholarships but it is nowhere near enough to pay for the full amount. I know that I will be in debt but I need to figure out a way to generate multiple sources of income somehow to let money flow within the 4-6 years I will be in college. When I’m done with schooling I don’t want to be suffocating in my debt so much where I won’t be able to do anything in life.
Venture debt ($12,240 a year): The first venture-debt fund has returned almost all my initial capital, so I decided to invest $200,000 in the second fund. I took a risk investing $150,000 in my friend's first fund, so I'm hoping there's less risk in the second fund, given he has four more years of experience on top of his 12-plus years of experience running a venture-debt portfolio for another company.

Although renting out your room or home can also be a side hustle to make extra cash, it's also a great source of passive income. However, another route to go is to get an income property just for the purpose of renting it out. This is even better if you live in a touristy area, because you can probably make even more than usual during the high tourist seasons.

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.
I don’t really know much about those…I should take a look from a diversification standpoint. If you don’t mind me asking, what do you target for your net effective tax rate on your passive income? Also, I’m sure you’ve probably covered this somewhere, but how do you deal with healthcare? One more dumb question…have you found that you spend more or less money than you anticipated once you retired?

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.
