I love to find what the book Awake the Giant Within calls Core Beliefs. BTW Danial Negreanu once called the book the best Poker Book ever.
If you don't know what a Core Belief is I will simply say that it is a foundational belief in the Hierarchy of beliefs we hold. It is a belief that other conclusion and other other beliefs are founded on. For example, if you believe all people are basically good or all people are basically evil, then that belief will be the foundation that a lot of your beliefs and conclusion in life will be founded on. So it can be said that identifying Core Beliefs can be important for understanding motivation and creating change.
Anyhow, one of my core beliefs is that Poker is an Art. But I suspect that a lot of people Core Belief is that poker is a Science.
