"Ne les laissez jamais vous voir craquer"

Simplified Meaning:

This saying means that you should always appear strong and confident, even when you are facing difficult situations or feeling stressed. It's like playing a card game where you don't show your opponents that you're worried or have a weak hand. In life, this can help you maintain respect and gain trust from others. For example, imagine you are giving a presentation at work. If you make a mistake, instead of showing panic or embarrassment, you keep your cool and continue confidently. This makes people believe in your ability and stay focused on your message rather than your mistake. Applying this to daily life means staying calm and composed, especially when things aren't going well. People are more likely to respect and follow someone who seems steady under pressure. By not letting others see you panic or give up, you build an image of reliability and strength.
