Yes, me.

My self-published book "Game Programming Patterns" has made me a lot more money every year for the past six years than I ever expected. It's not enough to live off of, at least not in an expensive city while raising a family, but it's nothing to scoff at either. I could probably make quite a bit more if I put time into marketing, supplementary materials, etc. As it is now, I just let the checks from Amazon etc. roll in and treat it as a nice bonus to my day job income.

If I lived somewhere cheaper, wrote full time, and made some adjustments in my lifestyle, I could probably get by on just my writing.

First, congratulations, thanks for publishing, thanks for sharing your experience!

Second, yes, maybe I was not clear, my advice relates to the average author on a simple straightforward method of write a book that reduces the odds of it not being of use of the audience it seeks.

Lastly, might be wrong, but it appears:

(A) at least on Amazon, your book appears to be rank in the top 20,000 of all books;

(B) you appear to have published a singular book;

(C) as you say, yourself, it does not make enough for someone to live in a major city;

(D) writing books is not your primary means of income;

—- to me, what I hearing does not conflict at all with my analysis and your example, to me is survivor bias: https://en.m.wikipedia.org/wiki/Survivorship_bias

Writing multiple best selling books year after year is VERY hard to do as a means of income. There are much easier ways to earn an income and share what you know. If someone wants to do that, awesome, though I do not have advice for doing that, nor do I know of anyone else that does; that would result in publishing 1+ successful books a year. My advice is just no nonsense take on being reducing odds of book being useful, which for the average author is much more of a challenge.

All of that is true, but it's also worth balancing that with the fact that when I was writing that book, I was only spending about an hour a day on it, and now I spend zero hours a day. The long tail of passive income seems to be pretty long so far.

You're right that it will be hard for many people to make a living solely off writing technical books. But I also think it's true that you can make more money that most people realize just by not giving a traditional publisher a huge cut of it. Maybe not enough to live on, but likely enough to make it worth your while.
