The "Upholder-class" is a personality type identified in Gretchen Rubin's framework of the Four Tendencies. Upholders are individuals who readily meet both internal expectations, such as personal goals, and external expectations, like deadlines or requests from others. They thrive on structure and often feel a strong sense of duty to fulfill commitments. Upholders are known for their reliability and discipline, making them effective in both personal and professional settings. They tend to enjoy routines and may struggle with flexibility when faced with unexpected changes. This class of individuals often seeks clarity and guidance to maintain their commitments.
