The word "事必躬亲" is formed through the sequential combination of four characters: 事 meaning "matter" or "affair", 必 meaning "must" or "necessarily", 躬 meaning "personally" or "oneself", and 亲 meaning "to do personally" or "to attend to". Together, they create a literal composition meaning "in matters, one must personally attend to them", resulting in an idiom that conveys the concept of taking hands-on responsibility for all tasks.
