Nice and concise! I just started Proof and the Art of Mathematics by JD Hamkins[0], based on pg's recommendation[1], "is a beautiful book in both senses. It's both beautifully written, but also physically beautiful, thanks to its many illustrations, which I was surprised to hear were made by the author himself." Chapter 4 on induction improved my attitude.
