In this book, the author describes his career path from apprentice gardener in a small Bavarian town to investment manager in the financial metropolis of New York. The detours along the way and the insights he gained into how to manage money sensibly make the book particularly interesting for laypeople who want to get a grip on their finances. At the end of the book, the "gardener of money" – as the author is described in a profile in the Financial Times – offers concrete suggestions for putting together a global stock portfolio and presents his "coffee can" strategy, a promising option for investing in stocks that anyone can understand.
