My plumber has an excellent business card. It says ‘Phil Jones’ on the top line. Underneath that is his job title: ‘Plumber’. It’s great because it tells me everything I need to know about what he does. He doesn’t try to dress up his line of work by calling himself a ‘Strategic Pipeline Analyst’ or an ‘Aqueous Substance Manager’. He does what it says on the tin. Your job title should do the same.
