His life is a joke. He can't study or do serious things. Doing tricks, doing bad things and ruining the family is a self-taught thing. Not only did he ruin an extremely wealthy family, he also pissed his parents to death.
Everyone thought he couldn't stand up, but they didn't expect that he could dive into the water without having to get up for a long time. He just turned around and rebuilt a rich family.
Book after book, generation after generation, his son is a complete reprint of his youth. He can't do serious things, but can learn crooked ways. He builds a family, but his son ruins it. He says that his life is a joke...
