"Una gran civilización no es conquistada desde fuera hasta que se ha destruido a sí misma desde dentro"
— Will Durant
Simplified Meaning:
When a society or country falls, it's often because of problems that start from inside it, not just because of outside attacks. Think about a big, strong tree. Even if a storm comes and tries to knock it over, the tree usually stands firm unless it is already rotting inside. In history, powerful empires like the Roman Empire didn't collapse only because of invaders; they also fell apart because of internal corruption, bad leadership, and social issues. To apply this to your life, consider how important it is to maintain healthy, strong relationships and a good sense of self. If you’re struggling inside with self-doubt or negative habits, it’s harder to face challenges from the outside. By keeping your inner strength and values intact, you're better equipped to handle anything that comes your way from the outside world. The key idea here is to focus on being strong and stable within, to better face external threats.
