"7 Habits of Highly Effective People" [1] - I listened to the audio book and it was really an eye-opener. It changed my perspective on people and personality a lot. Highly recommended. Same with the book "How To Win Friends And Influence People" [2]. It's written decades ago and still holds the principles true. Another gem I found recently was : "How to Stop Worrying and Start Living" by the same author of [2]. It's really good if you are stressed with your lifestyle. Really gives practical advice.
