Sometime ambivalence can be a simple as making simple decision between getting out of bed and exercising or staying there. Sometimes an act of will is better then a paralysis noted below.

This often comes out in an inability to decide. People often are torn between different options: They see both sides and weigh arguments for and against each side, and they still can't decide; finally they find themselves acting one way or the other or, perhaps, they flip a coin or consult a psychic or follow the advice of a friend or teacher. Or an ambivalent person can move in one direction and then hesitate and then move in another direction and then hesitate and so on to the point where he or she is caught in a kind of paralysis.
