As the German poet Theodor Fontane once said, “A good aphorism is the wisdom of a whole book in a single sentence”. The aphorisms and other quotations collected by Dr. Rainer Zitelmann on this website bring together insights and experiences from the past two millennia. The quotations include classic philosophers, contemporary writers and successful entrepreneurs, as well as scientists and artists. Dr. Zitelmann has added personal commentaries to the quotations to place them within the context of our every-day challenges and opportunities, especially those we encounter in our professional lives, but in our personal lives, too.
Previous books by Dr. Rainer Zitelmann include “Dare to be Different and Grow Rich”, which has been translated into a host of languages worldwide. Aside from this book, he is the author of 17 other books on subjects such as history, politics and economics, and these too have been translated into many languages.
He obtained his doctorate in history, graduating “summa cum laude,” and went on to teach at the Free University of Berlin.
