1. At any given point in their lives, people do things the best way they know how.
2. Most people never reach their full potential.
3. Most people do not know how to reach their full potential, but they can learn.
4. Becoming fully yourself requires getting out of your own way--removing the blocks to achievement.
5. Much of life is a self-fulfilling prophecy.  Henry Ford stated it this way, "Whether you believe you can, or you believe you can't, you're probably right."
6. The mind and body interact in both positive and negative ways--to both empower and disempower.
7. You are largely what you make yourself to be--you must take personal responsibility for your own performance.
8. The goal is self-realization, the process of becoming the best you can be.
9. Nothing works every time--human behavior follows the laws of probability.

This list is a summary of some assumptions that underlie the principles presented in a "Human Performance Enhancement" class I recently completed.  Credit for this list belongs to Ronald Smith of the UW psychology department.  To my knowledge, there is no research to support or deny these claims; however, this list provides an interesting and provocative perspective on human behavior.
