Value

 I think it is normal to want to feel that we are of some value, that is validated as to who we are and/or what we do.  But there is a difference in being validated by others,  rather than trying to be validated by ourself.  This is where addiction can rise up and bite us.  Someone comes into a group and feels like an outsider, unimportant, unnoticed.  So they start to drink, and as they drink alcohol, their personality, manner and self-perception change.  They feel like the center of attention.  It is validation by overindulgence.  It can happen with work, or even doing good for others.  When it becomes overindulgence, we know that the action is devaluing us.  Moderation.  And if that is impossible, abstinence.
