What this quote means

Plato places victory over oneself as the highest. Before seeking to dominate others or the world, we must first master our own impulses, fears, and desires. This inner conquest is the first and best because it conditions all others. Without it, our external successes remain fragile and dependent. It makes us masters of ourselves, an essential quality for any lasting achievement.

How to apply it daily

Start your day by setting an intention of self-mastery. When faced with a challenge, choose the response that reflects your values rather than your impulse.
