1. Life conditions must be as I want them to be. If they are not it is awful, terrible and unbearable.
2. You absolutely must treat me nicely as I want you to treat me. If you do not it is awful, terrible and unbearable and you are a rotten individual. Afterall, I am the center of the universe.
3. I must perform well and possess all or at least most of the desirable characteristics I must possess to consider myself worthwhile and adequate as a person. If I do not perform well and possess all or most of these desirable characteristics I am less worthwhile and inadequate as a person.
If you keep your wishes AND wants regarding how life conditions, other people, and even yourself ideally could be but never have to be then you can have some degree of happiness even when things are not as you want them to be. Some degree of happiness when facing adversity or less than ideal conditions is nearly always a choice. Choose wisely!
