What is a one book that you consider essential for every startup enthusiast?

I am reading "done" right now and it seems pretty great for remote-centric teams focused on staying remote.

I'd say "The Lean Startup" by Eric Ries is almost like a startup bible.

I think it does the brain good devote some time to escaping into some fiction so recommending some of my favorite summer reads: Project Hail Mary by Andy Weir, Tomorrow, and Tomorrow, and Tomorrow (Gabrielle Zevin), Babel (R.F. Kuang)
