Adjustment shock is the unsettling emotional discord that arises from even positive life changes. This term is discussed mainly in Chapter 4, which focuses on building emotional intelligence. It highlights the discomfort people often feel when something new enters their life, even if that change is positive. The term is a lens through which the reader can understand the complex emotional responses that may accompany progress, emphasizing that discomfort doesn’t necessarily signify a wrong decision.

Defined as life’s challenges or obstacles, adversity is the central motif of the book, represented metaphorically by the “mountain” of the title. Adversity is not necessarily negative; often, it is an opportunity for personal growth and self-fulfillment. It is the force that can lead to “positive disintegration,” a transformative process helping individuals become more self-aware and resilient.

Core commitments are the underlying principles that guide one’s actions, often operating from the subconscious. These are closely linked to core needs, which are foundational emotional and psychological requirements. The book argues that understanding these elements is essential to addressing and overcoming self-sabotaging behaviors.
