"Well-being" is a nurturing, caring kind of positive emotion most akin to being "maternal" or motherly toward one's self and others. It is the specific antidote to one of the two types of stress, called, "hurt." Well-being is then the opposite of
Well-being is then the opposite of hurt, and is a kind of "potential energy," or a resource reserve whose exact amount is the same as the amount of "hurt" that one may bear without falling into the negative emotions of anger and sadness in response.
To have a complete and well-rounded self-esteem, one needs both well-being and confidence in order to be fully happy, and capable of lasting friendship and love with others.
Kings and Queens (Phlegmatic personalities), as well as Lovers (Melancholic personalities), are dominant in this self-esteem type, and they are good at nurturing and lending comfort to others as an emotional resource of friendship and love. Those who lack this self-esteem type are the Warrior and Magician personalities, also called the Choleric and Sanguine types in Galen's system of personality. In friendship and love, Kings, Queens and Lovers make good emotional matches for Warriors and Magicians.
The opposite of well-being's positive emotional energy is the negative emotional energy in the type of stress called, "Hurt." Hurt feels like an outside threat has come in to do you harm or damage to your happiness, and can take any form from the insulting words of a bully to the physicality of a slap to the face, or a bee-sting. Since self-esteem and its subtype, well-being, are forms of emotional or chemical energy, the laws of thermodynamics rule over their dynamics, and so the exact amount of hurt that stresses a person, and gets in through one's personal boundary, is the same as the amount of well-being that will be depleted by that hurt.
As a result, one may find themselves needing to recover from and rejuvenate from hurtful stresses and episodes, by transforming it into a positive, by a decision to use the assertiveness that is described in the Anger Map. Kings, Queens, and Lovers may have a natural gift for doing this transformation if they are mature people, but if one feels sad, victimized (and therefore anxious) on account of a hurtful stress, the depletion of the energy of happiness needs to be recovered from. The personal boundary is the first line of defense against this, but even it can weaken.
Mastering these tasks, and of the Anger Map (viewed as a treasure map for getting our needs met in life), is one of the major steps of both friendship, love and emotional attraction, as well as forming part of step five of human courtship in general, "Finding Stress in Each Other."
