Last winter, I went with my family on holiday to Switzerland. While we were unpacking, I found a book called “Stumbling on Happiness” belonging to my father. I started to tease him a bit and said that is was silly that he needed a book to become happy, but after a few days I became very curious and started to read the book. I discovered that “Stumbling on happiness” was not a self-help book for unhappy people as I expected before, but that it was actually very interesting. Therefore, I would like to tell you something about predicting the future, one of the many things the book is about.
