"勇気は偽ることができない唯一の美徳である"

Simplified Meaning:

Courage is something you have to really feel and show. You can't pretend to be brave because true courage shows in tough situations. Imagine you are in a burning building. If you pretend to be brave but feel terrified and do nothing to help, people will see there is no real courage. Being brave means you act, even when you are scared, and others can see the difference. For example, think about firefighters. They go into dangerous places to save lives, even though they are also afraid. Their bravery is real because they face the danger head-on. If someone just pretends to be brave but runs away at the first sign of danger, everyone will soon know it is an act. So, showing courage means doing the right thing when it’s hard, and that’s something you can't fake. In your life, whenever you face a difficult challenge, remember that true bravery is about taking action and not just looking fearless.
