The only way to deal with an unfree world is to become so absolutely free that your very existence is an act of rebellion.
It's not the length of life, but the depth of life.
Whatever you do, enjoy it to the fullest. That is the secret of life.
The true measure of a shinobi is not how he lives but how he dies.
You should enjoy the little detours. To the fullest. Because that's where you'll find the things more important than what you want.
