I completed first book of 2021 already few days ago (but then again started it in 2020 🙃)
To Sell is Human is a nice, practical book about how (purportedly) everything we do professionally is, in essence, sales. While I find some of the scientific justifications a bit light on the details I also find exercises and practical advice it gives very good. Will revisit the exercises chapters in the fitir when I need to something sales related.
I am now reading ”The Light Fantastic” be Terry Pratchett and starting Aristotle’s Nichomachean Ethics
