The core philosophy of Cognitive Behavioral Therapy (CBT) can be summed up by a quote from the Stoic philosopher Epictetus: "Men are disturbed not by things, but by the view which they take of them."
CBT is a structured, goal-oriented form of psychotherapy that focuses on identifying and changing negative thought patterns and behaviors.
While traditional therapy might look into the distant past, CBT/REBT is focused on the "Here and Now." It provides clients with a toolkit to become their own therapists by understanding the mechanics of their own minds.
