Enneagram Type One, often referred to as "The Reformer," or "The Perfectionist," has a personality type characterized by a strong sense of integrity, morality, order, and excellence. Individuals of this type are driven by a deep inner desire to improve themselves and the world around them. They have a strong sense of right and wrong, and they are motivated to make a positive impact on society.

Type Ones are often seen as responsible, reliable, and conscientious individuals. They are committed to doing what is right and are willing to work hard to achieve their goals. They can be excellent leaders and are often found in roles that require a strong sense of purpose, meticulousness, and responsibility.

Type Ones are principled and often have a clear set of values that guide their actions and decisions. They hold themselves to high standards and can confuse their desire for excellence with perfectionism. As a result, they are often their own harshest critics. This self-criticism stems from their desire to be perfect and to avoid making mistakes. It can be a source of stress and frustration when this inner voice continually evaluates their behavior and the behavior of others.

Paradoxically, as Enneagram Type Ones learn to relax their need for constant self-improvement and realize that imperfection is a natural part of life, including making mistakes, they become beacons for true change in the world. Life is no longer defined in black and white terms, and their natural gravitas fuels a sense of dignity and humanity within all those they touch.
