@raghav2 "Thae Four Agreements" - it's an easy read and might seem very spiritual (not sure where your'e coming from) - but it's very eye opening in my opinion. And on the business side - you've got the "The Lean Startup" which is super interesting, and if you want an interesting read about the world of smart speakers - read "The Smart Wife". I loved it and keep quoting from there :)
