Another thing is that man is mostly selfish, and what interests him is that which concerns his own life; not knowing the troubles of the lives of others, he feels the burden of his own life even more than the burden of the whole world. If only man in his poverty could realize that there are others whose sufferings are perhaps greater than his; in his troubles that there are others whose difficulties are perhaps greater than his! Self-pity is the worst poverty. It overwhelms a man, and he sees nothing but his own troubles and pains; and then it seems to him that he is the most unhappy person, more so than anyone in the world.
