The Three Majors Musts - http://www.rebtnetwork.org/library/musts.html

We all express ourselves differently, but the irrational beliefs that upset us can be placed under three major headings. Each of these core beliefs contains an absolutistic must or demand. These three majors musts can be summarized as follows:

I. I must do well and win the approval of others or else I am no good.

Summary

Inflexible
Places unrealistic expectations on oneself
Over-concern with others' opinion of oneself
Self-worth measured by achievement and popularity
Non-self-accepting

Sub-beliefs
I must have love and approval from everybody.
I need someone to love me.
I must not do anything that would cause others to think less of me.
I must be competent and successful.
I must have an important skill or talent.
I must successfully avoid unpleasant or undesirable situations.
Unpleasant and undesirable situations upset me.
I can't control my emotions in difficult situations.

I must think, feel and act the same as I always have.
My past has such a strong influence on me that I cannot change.
I must find order, certainty, and predictability in life.
If I don't find these things, I cannot feel comfortable or act competently.

I must rely on superstition and religion especially in difficult times.
I must understand the secrets of the universe.
I cannot be happy unless I understand the nature and secrets of the universe.
