There has been a lot of buzz around Cognitive Behavioral Therapy (CBT) in the past several years, and many great self-help books and mental health apps have centered around the concepts of CBT. A key component of CBT is the Cognitive Triangle. This is the concept that thoughts, feelings, and behaviors all work together to influence each other. By working to target any of the three points on the triangle, it will naturally impact the other two. In therapy, the most common means of doing this is by challenging irrational thoughts in order to change feelings and behaviors.
