A One sees how things should be and feels duty-bound to get them there. They are principled, meticulous and reliable. Inside, though, they often hear a harsh critic that never lets up.
Ones have a strong sense of what is right and fair. They notice mistakes and imperfections before anyone else and want to fix them, at work, at home and in society. To the people around them, they come across as someone you can count on.
Behind the drive for perfection lies a fear of getting it wrong. Ones often don't allow themselves to show anger, because they see it as bad. Instead, it comes out as irritability, criticism or tension in the body. What helps them most is discovering that “good enough” is often enough.

Full wing profile →Subtypes

One-to-one One
Fervent
They turn their energy outward: they want to fix others, especially those close to them and their partner. They have more fire and directness and less patience than the other Perfectionists, and they feel they have the right to change things. Anger is most visible in this subtype.
