There are many deeply affecting words in "Naruto". I have listed three sentences below, all of which can touch me.

People... can become really strong when they want to protect important things. ——Bai

Everyone has their own fragile side, but they also have a strong side. That should be the time to protect your important things! Everyone's important things are different. Some are parents, some are friends, and some are lovers. They may be your safe haven when you are vulnerable, the hand that comforts you when you are sad, and they can also make you strong. People, you can cry at them, laugh at them, quarrel with them, and make a fuss with them, but you don't allow others to bully them, because they are your most important people.

People who don’t believe in themselves don’t even have the value of their efforts. ——Kay

You are the person who knows yourself best. Everyone in the world may hurt yourself, but you are the only one who will not hurt yourself. Therefore, you have to give yourself enough trust. If you don’t believe in yourself, then who else will believe in you. Only when you have confidence in yourself can you have the motivation to work hard. Let me ask, a person who does not believe in himself, always doubts himself and has low self-esteem, what is the value of his efforts? His efforts will only make the gap between himself and others wider and wider, because he is not confident, does not believe in himself, and does not dare to try. Therefore, self-confidence is the first step to a person's success, and hard work is the second step. However, blind self-confidence will turn into arrogance and stop your efforts.

We call people who violate the ninja rules a waste. However, those who do not know how to value their companions are worse than trash! - Kakashi Obito

Companions are important to us. As the saying goes, "United strength is great", "When everyone adds fuel, the flames are high", etc., etc. all talk about the importance of the team.
