I see learn something cool about life, just simple life from nara shikamaru.
"I just want to life like clouds, keep calm and free, I just want to marry a regular girl who isn't too ugly and not too pretty. Have two children, first a girl, then a boy. Retire after my daughter is married and my son becomes a successful ninja, and spend the rest of my life playing shōgi or Go. Then die of old age before my wife"
You know, I life is is so simple, that's your choice, do you choice to be happy or not ? Just living your life before you die, We knows everyone has to die someday, so just living until that's happen
