— Self-esteem and self-worth can be be quite similar. Some people use the terms interchangeably, while other people feel that self-worth is a more global, deeper feeling.
I can only be quite general here…
When we hold someone in “high esteem” we think highly of them for some reason or another. Perhaps they are a good role model as a parent, or they are good looking person, or they are smart. Those are things that make a person think “well” of someone. So self-esteem comprises the things that a person things about him/herself that gives them a sense of thinking well of themselves. I think self-esteem can come from doing things and our achievements, the way we have done something, personal traits that we feel make us better people, how other people react to us, what we think of our bodies/appearance, etc. Self esteem might come from earning an A+ in a difficult subject. Or from earning a B- when we have really worked hard to get that B-. Maybe we are attractive or have a great sense of humour. All of those things and more can make us feel good about ourselves and boost “how we see ourselves” — our “self-esteem.”
Self-worth is the value we place on the above things: do they add to our meaning and purpose in the world? Some simplified examples: I get self-worth from volunteering and helping others; contributing intelligent conversation in my book club; leading a cause in the community; being conscious of my ecological footprint (use of plastics, gasoline, food). My self-worth tells me I am valuable because I care about these things and act with them in mind.
Does that help any? You might want to google “psychology, self-esteem, self-worth” and read some professional discussions about the definitions.
