The Keeper

You do what you said you would, properly and on time. You trust proven experience over an idea that merely sounds good.

Accounting, audit, administration, law, logistics, engineering, quality management.

Relationships

You show affection by being dependable rather than by saying so. Say it occasionally — actions do not translate themselves.

Where to grow

Each quarter, try a new way of doing something familiar. Your steadiness is a strength, but it needs periodic testing.

A note on trademarks and use: MBTI® is a registered trademark of The Myers & Briggs Foundation. The test here is not the official MBTI® instrument — it is built on the four dichotomies in Carl Jung's typology, with questions we wrote ourselves. Treat the result as a prompt for your own reflection rather than a diagnostic, and do not use it to select or screen anyone at work.
