$477,916 for writing a boring book

Martin Kleppmann spent 2.5 years writing a book called Designing Data-Intensive Applications.

Doesn’t exactly sound like a thrilling read, does it? 😂

And yet he reports that he’s earned almost $500k from the book so far.

Unfortunately, he also reports that “the success of my book is atypical.”

And:

writing a book is really hard, at least if you want to do it well. For me it was about the same level of difficulty as building and selling a startup, that is to say, involving multiple existential crises. The writing process was not good for my mental health.
