“Self” is always define as the personality of a person. A personality is created by millions of memory clips, that is, what happened to the person can make him or her to be what kind of person. For example, if a person lives in a wealthy family and has smooth and wellfed life, he or she must have a outgoing personality that always being optimistic, and never worried about everything because there is always someone help he or she to clean up the mess he or she caused. This kind of person has the personality that always being gluttonous and lazy; the memory clips of being brought up in the lap of luxury causing them this personality.

However, if a person lives in a poor family and lives in a hardship, he or she probably works harder than the kind of person I mention above. Some of them even get bullied by others because of their situation. This kid of memory clips might probably bring negative experience to these people. In this way, this kind of person might be more bashful and timidity than the people from wealthy family.
