I adopted quite a bit of japanese mentality, prioritizing harmony of a group now over self-affirmation. It's a double edged sword though. I'm bad at reading the air and can't handle arguments or direct criticism well.
My personality hasn't really changed much since I was about 8-9. Incredibly anti-social, very lazy, very coarse in all manners.
Well.. Devil May Cry is a video game but everyone says it's animesque. I found the lead character Dante's laid back attitude and heart of gold in the face of his fractured family and constant fighting inspiring, since I had a family that fought and backstabbed each other so much. The rewarding difficulty of the game taught me to be both a go-getter and patient. I know that's a lot for a goofy action game, but looking back I think it made an impression on me, as I've been a fan of DMC since I was about 7 years old.
