All wealth is the product of labor.

“唯一真正无限的是人类爱的能力。”

I'm the reason you're alive, I'm the reason you survive.

Our frustration is greater when we have much and want more than when we have nothing and want some. We are less dissatisfied when we lack many things than when we seem to lack but one thing.

译文：贫穷到没有办法时，只要节俭还可以度日。天资愚钝也没有什么大不了，只要勤奋，也能弥补它的不足。赏析：自身条件不行，就要时刻警醒自己，发愤图强。如果破罐子破摔，躺平摆烂，事情就会变得更加糟糕。

幸せは、小さな瞬間の積み重ねだ。
