"Nous nous ruinerons dans la vaine recherche de la sécurité absolue"

Simplified Meaning:

Trying to be completely safe from every possible danger can cost us too much and leave us with nothing. Think about how some people might spend all their money on security systems, insurance, and safety gadgets because they are afraid of bad things happening. While it’s important to be careful, if they spend too much, they might end up with no money left for basics like food or health care. For example, during the Cold War, countries spent huge amounts on weapons and defenses to feel secure against each other. This didn't just cost money; it also created lots of stress and fear, and in many ways, didn't make people feel safer at all. People can use this idea in everyday life by balancing their efforts to stay safe with being practical about their resources. Instead of worrying too much and investing all their time and money into staying safe, they should also focus on living their lives and enjoying the present moment.
