Actually, on Naruto. I didn't read much manga outside it. But enjoy I did Naruto. There was so much drama, injustice, vengeance, and rivalry that I just couldn't stop reading it. And within that drama and plot twists there were some useful lessons. At least I think so.
The whole theme of Naruto was the first lesson for me. He was a loser, who wasn't going to achieve great things in life. Everyone including his teachers thought so. He was jealous of his team mate prodigy, Sasuke, and it seemed he would never catch up to him. But through hard work and persistence (and admittedly some luck) he became the village's hero.
We've heard similar tales or stories many times before. What I loved about this one is that Naruto's signature jutsu (power move) was his greatest weakness in the beginning. He couldn't master this jutsu and was humiliated when he failed his academy exam because of it. But in time and after hard work it became his most powerful move, his greatest strength. I liked that. I liked the idea that instead of running or shying away from our weaknesses, we should tackle them head on.
Thanks all and love
