"男は自分の過ちを認めるのに十分な大きさを持ちそれから利益を得るのに十分な賢さを持ちそれを正すのに十分な強さを持たなければならない"

Simplified Meaning:

When someone makes a mistake, it's important for them to recognize and accept that they did something wrong. This takes humility and honesty. Once they see their mistake, they should use the experience to learn and gain wisdom, figuring out how to avoid doing the same thing again. Finally, they need the courage and determination to take action and fix what went wrong. For example, imagine a student who fails an exam. First, they need to admit to themselves and others that they didn't study enough. Then, they should look at what went wrong and find better ways to study. Finally, they must work hard and use their new study methods to improve their grades. By doing so, they not only become better students but also develop important skills for life. This approach can be used in work or relationships, helping people grow stronger and wiser from their mistakes.
