Soyez prêt - Le manuel pour survivre aux pires catastrophes

The book emphasizes psychological preparedness as much as tactics. I'm curious what personal experiences or insights led to this balance.

The manual covers so many scenarios that I wondered if all of it is practical for everyday prep or more for extreme situations.

There are many books out there, but this one seems to blend personal development with tactical advice. Would love to hear others' take on its usefulness.
