This document discusses self-esteem and its various components and characteristics. It defines self-esteem as having three meanings: global self-esteem referring to one's overall feelings of self-worth, self-evaluations of one's specific abilities, and momentary feelings of self-worth from experiences. High self-esteem is associated with having a clearly defined sense of self while low self-esteem can lead to self-concept confusion. Experiences of failure negatively impact low self-esteem more than high self-esteem. Self-esteem also influences self-handicapping tendencies and is shaped by both individual and sociological factors.
