I earned $160k in passive income from writing non-fiction books
Writing (from a quick skim check) at least 16 books over a period of 6 years, and earning money from that, is not exactly what I&#x27;d call &quot;passive income&quot;. And given the topics are mostly (all?) about niches in current technologies they also won&#x27;t continue to deliver passively forever.<p>A more appropriate title and angle might be &quot;How I&#x27;ve earned $10k&#x2F;book and manage to keep writing more while maintaining a day job&quot;. (Which is in itself impressive!)
