Cognitive therapy is based on the idea that when you change the way you think, you can change the way you feel and behave. In other words, if we can learn to think about other people in a more positive and realistic way, it will be far easier to resolve conflicts and develop rewarding personal and professional relationships.

Every time you feel depressed about something, try to identify a corresponding negative thought you had just prior to and during the depression. Because these thoughts have actually created your bad mood, by learning to restructure them, you can change your mood.

Learning to accept failure on multiple levels is, to my way of thinking, the key to become a world-class therapist. But that means humility, and setting your ego aside, while you develop superb new technical skills.

One of the most interesting things about the cognitive theory is the idea that anger and interpersonal conflict ultimately result from a mental con. In other words, you're telling yourself things that aren't entirely true when you're fighting with someone.
