My own experience convinces me there are many extra benefits to having written a book. My first book has been out for 4.5 years now. I know many people on Hacker News have read it and I'm grateful to all of you.I've enjoyed getting emails about it. Especially regarding "badly managed startups" and "abusive bosses" many of you have reached out to share similar stories. Maybe at some point I'll do a blog post that collects some of those email stories. Some people thought I was destroying my career by revealing the dark side of startups, but some entrepreneurs appreciate my realism and practicality, so I've gotten three very lucrative consulting jobs, thanks to that first book. And, surprisingly, the book has gotten more and more popular. It sold more this last year than it sold during its first two years. I assume that at some point the book will seem dated and obsolete, but at least for now it still strikes people as current, so the benefits of writing that book continue to pay dividends.
