"自分自身の過ちを他人の過ちよりも正す方がよい。"
— Democritus
Simplified Meaning:
Focusing on fixing your own mistakes is more important and beneficial than pointing out or criticizing the mistakes of others. Imagine you are in a group project at school, and instead of correcting your own errors in your part of the work, you spend all your time finding flaws in what your classmates are doing. In the end, your own work suffers, and the project as a whole might fail because you didn't take care of your own responsibilities. Similarly, in life, making sure you improve yourself and learn from your own errors helps you grow and do better in the future. It also makes you a more positive and supportive person, which others appreciate. When you focus on your own growth, you'll find you're more capable and less bothered by the mistakes of others.
