The Stoics believed in the virtue of consistency as an integral part of leading a fulfilling life. They held the view that consistency in thought and action enabled a person to align with their inner nature and the natural order of the universe.

This consistency wasn't just about routines or habits, but rather about maintaining a consistent internal state, adhering to a set of ethical principles, and responding to life's challenges with equanimity.

They saw inconsistency as a sign of internal discord, which could disrupt tranquility and hinder one's path to wisdom and virtue.
