Mentor Byte
Stop memorizing lists of jobs — ask one question instead: does this job extract, make, or serve? Pull something from the earth, and it's Primary. Build or process something new, and it's Secondary. Move, sell, or care for someone, and it's Tertiary. Master this lens, and no exam can trick you on sector classification again.
For Parents
Ask your child to trace their breakfast backward through all three sectors — it turns an abstract concept into a game they can play at the table.
