I agree. I DID write a book! https://howtoopensource.dev/

My biggest tip is this: Don’t skip getting beta readers. High quality feedback is really hard to come by. I changed my tool chain to add a google form at the end of each chapter and got strong buy in from a handful of people with the finished first draft in a beta state. In the end some bailed but one left amazing feedback resulting in massive structural changes.

The process of writing a book is two things (to me). The most obvious is sharing information. The second, often overlooked, but biggest benefit IMHO is how you will grow and learn the source material even better than you already do. Even if you don’t ever publish it, it’s still worthwhile to putting in the effort to write a book. GLHF.
