Aaron T. Beck quotes:

Some authors have conceptualized depression as a "depletion syndrome" because of the prominence of fatigability; they postulate that the patient exhausts his available energy during the period prior to the onset of the depression and that the depressed state represents a kind of hibernation, during which the patient gradually builds up a new story of energy.

The stronger person is not the one making the most noise but the one who can quietly direct the conversation toward defining and solving problems.

Cognitive therapy seeks to alleviate psychological stresses by correcting faulty conceptions and self-signals. By correcting erroneous beliefs we can lower excessive reactions.

As applied to substance abuse, the cognitive approach helps individuals to come to grips with the problems leading to emotional distress and to gain a broader perspective on their reliance on drugs for pleasure and/or relief from discomfort.
