Adept means very good at something — but not at just anything. It is for skills that need practice, care, and a bit of cleverness: playing an instrument, handling difficult people, cooking, fixing machines, arguing a case. You would not normally say someone is adept at sleeping or adept at eating. The word points at a skill that was learned, and learned well.
