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.

- Limited discussion until the end of the book (p. 290) about Sequence of Return Risk. This is something few people understand and it is flat out dangerous to lead someone to potentially believe that they can retire decades earlier than "standard/normal retirement age" with significantly less money than they would supposedly otherwise need to accumulate by age 65, immediately starting withdrawing from these funds, and that their money will likely double, triple, or quadruple by the time they're much older. Yes, this is possible IF someone can remain flexible (on taking withdrawals from their assets, on generating income in "retirement"), IF someone has alternate income sources, IF market conditions are generally favorable during at least the first decade of "retirement," etc., but there is a major risk here as well. The author does mention these items and does provide a few cautionary words, but I do not think this was stressed enough for the average reader to truly understand the complete impact/considerations. I feel like most people will think, "oh, awesome, I can retire in my 30s with $1.25M, starting taking withdrawals right away, never run out of money, and my portfolio will be worth multiples of the $1.25M in my later years." More time should be spent discussing sequence of return risk.
