It is the combination of lightness and depth making for me the interest of the book. The lightness because the style is simple, familiar, because it is in the concrete, daily, current, because humor is underlying. Depth because reflection is philosophical, as you approach the change, universal, complexity and poses the question of meaning. The book gives depth to the simple things.
It therefore opens up prospects for philosophize by yourself. To this I perceived as a sort of initiation story or training exercise, to use sport. It is loaded with hope, it gives confidence, starting with self-confidence.
I had the impression of wisdom for our time in the tradition of "wisdom literature"
