If you could recommend just one book that everyone should read, what would it be?

Tough to say. "How to Win Friends & Influence People" IMO is a classic and should give you a good foundation in life, communication & relationships - which are key to any business. I'm also launching SaaS Bookshelf soon, a curated list of 100+ books with key takeaways for founders. Thought this might be useful to the readers here!

"Mastery" by Robert Greene. I really believe that it will help you understand all about passion, find yours and actually start working towards becoming a master in it. If you ask me, achieving the above can be pretty satisfying :) @balkrishna_karma1 I've only heard about the book recommended, but still haven't tried it. Definitely on my list!

I also like sapiens! How about michael sandel's justice? it break my streotype of Humanities.
