All traits of a human being must derive from somewhere or someone. In this instance, Okonkwo’s father was known as a failure, and therefore the catalyst for Okonkwo’s fear of failure. When the father was still alive, he continuously made poor finical decisions, leaving his family to care for themselves.
In the future, I predict that Okonkwo’s obsession with weakness will challenge him to overcome larger obstacles through out the novel. Although his tribe is strong, perhaps a large enough threat of either physical violent or mental challenges will present themselves.
