A book that has had a very strong influence on my life. Dale Carengie is definately the master of self-help books: Despite being a old book (released 100 years ago) the principles tought are still relevant and powerful. In this book, Dale Carengie gives you simple DOs and DONTs in human relationships: What people like or don't like to hear, and how to say it. From subtle tips like remembering a person's name, to giving him a title which he will try to fulfill. This book has definately improved my relationships with people. I recommend it without any doubt.
