Type One - The Perfectionist

Type One: The Perfectionist

Ones, often called Perfectionists or Reformers, feel a compulsive need to improve the world around them. Ethical, dedicated, and reliable, they are motivated by a desire to live the right way and avoid fault and blame. Residing in the Gut Triad, Ones internalize anger, which often bubbles up as smoldering resentment when others don’t live up to their impossibly high standards. But don’t think they let themselves off the hook—Ones live with a constant awareness of their own inner critic, reminding them of all the ways they’ve failed.

At their best, Ones have an amazing ability to see potential improvement in everything around them and also take the action to bring that vision to fruition. At their worst, Ones can be overly critical of themselves and others, leaving everyone feeling as if they don’t measure up.
