Hector and the Search for Happiness by Francois Lelord
Hector is a psychiatrist who sets off around the world determined to figure out what makes people happy. He travels to China, Africa, and the US, interviews people and jots down his observations in a notebook.
The writing is simple and the chapters are short, but it got a bit tiring at the end. This book reminded me some of Antoine de St. Exupery's The Little Prince because it's whimsical. There is another book that follows this one, but I'll pass. This one was enough for this bear.
