Survival: this refers to taking care of oneself by eating, drinking, seeking shelter, and resisting illness.
Belonging: this includes the need to love, to share, and to cooperate and is found in all cultures.
Power: the need for power and the need to be better than others often conflict with our need for belonging. For e.g., our need to be powerful in a marriage conflicts with the need to be loved by one's spouse. Glasser believes that it is not insufficient love that destroys relationships, but the power struggle; the inability of husbands and wives to give up their power and negotiate compromises.
Freedom: this refers to how we wish to live our lives, how we wish to express ourselves, whom we wish to associate with, where we worship, what we read etc. If an individual has a need for freedom that is so strong that he has no significant relationships with others, then the need for belongingness is not met and the individual is likely to feel lonely.
Fun: the need for fun is not as strong a need as that of survival, power, freedom, or belongingness, but is still an important one.
