Literally, your self esteem is the esteem in which you hold yourself. If you perceive yourself to be inadequate, unworthy, unable, etc, you hold yourself in low self esteem. This will probably affect your behavior and how you communicate with other people. You might find it harder to look people straight in the eye, and you might fidget if you feel nervous. People may think of you as nervous or timid and less likely to recommend yourself for a pay rise, or to easily put yourself forward for a promotion. You might also let others walk all over you.
Sometimes we can go through periods when life is a bit tougher, perhaps after a divorce, or relationship breakdown. A situation like this, or perhaps losing a job through a company downsizing or relocating clearly not something for which we can be held to account, can lead to a temporary loss of self-esteem.
So self-esteem is not a fixed thing. Our lives are generally full of change. We begin, as does everyone else, as a child, and very dependent upon our parents and other adults. Part of this dependency is for approval, love and support for nurturing.
If we are fortunate, we are treasured, made to feel comfortable in our achievements and failings. We can’t all be top of the class, or make the school sports teams. We may achieve things some of the time, but not all the time. Many people are highly valued in their lives, their work, and their social networks, but this is not dependant upon coming first, getting medals.
If on the other hand we are unfortunate and don’t have kind, loving and supportive parents, maybe it is because they don’t understand how important self esteem is. It may be that our parents don’t have the self confidence to enable them to help us. We learn to assess ourselves also by how our teachers and friends treat us. We might have a great home life, but for some reason get picked on by a bully or group of bullies, and as a result can be scared, and feel our self esteem drop like a stone.
The main thing is to see our self esteem as something that we can affect ourselves. We can learn to recognize when our self esteem is getting a bit delicate, and when we need to give ourselves a boost. Positive thinking and a positive attitude is now recognized as a very valuable tool in managing our lives. This can benefit ourselves individually of course, but it is also important in that it can benefit the lives of those around us, and particularly those who depend on us.
Of course some people appear to have oodles of self esteem really worryingly too much self esteem in fact. They behave as if they are the only people on the planet. This is not a good level of self esteem if it makes a person too selfish or too demanding. If someone doesn’t respect the people around them, and only respects themselves, they have an unhealthy level of self esteem.
This unearned self esteem has been linked with bullying, violence and aggression. A too high opinion of ones self can result in unpleasant behavior to others, aggressive language and mannerisms and being overly loud and opinionated. . If we become really only concerned with ourselves, our own rights and entitlements, we are showing signs of excessively high self esteem.
So what we need to aim for is a healthy level of self esteem. Not too much, and not too little. With a healthy level of self esteem, an individual is likely to have a sensible view of their character, their ability, and their potential. Being able to make sensible evaluations of ourselves and others is far less stressful than having an overly high or low view of ourselves.
With a healthy level of self esteem we can more likely maintain calm, rational thought processes and behavior. We can deal with difficult situations more easily if we have a reasonable level of self esteem. We are less likely to become defensive or aggressive, and we are less likely to appear flustered, bombastic or nervous. Calm behavior is likely to result in others feeling more confident in us.
So it is definitely in our interests both in feeling better in ourselves and the realization that others will feel more comfortable in our company, if we have a good level of self esteem, neither too high, nor too low.

What exactly is self-esteem? Is it a real concept or just another psychotherapists’ invention?
So far it comes as exactly the same as good social skills, assertiveness, self-perception and knowledge of oneself. Somewhere, somehow there must be something else, otherwise I am not truly and fully convinced it exists on its own.
am wondering the same thing!…. i adore ltho i am as a person , but i have social problems and shyness….and lots of stuff al mixed up …….i dont know if its low self esteem r high

To me "self esteem" is feeling like you are "worth" something, and that you feel that you can make a valuable input to your suroundings too.
I didn’t have much self esteem when I was younger and let people use me and I didn’t complain about things much, because I thought that was how life was and I couldn’t hope for anything better. Then, one day, I kind of woke up and said, "what the hell am I doing ?" and I started telling people "no" when they were asking me for things and I started standing up for myself. My life is alot better^_^.

Self-esteem is a psychology term, though not an ‘invention’. The concept has been studied and labeled by researchers, but it usually isn’t considered an invention.
Self-esteem is a personality trait, and is considered a long-term trait, not a temporary one. There can be short-term fluctuations, but people tend to have the same general trend in their self-esteem, unless they actively work to change it (through therapy or self-help).
Basically, it’s a description of your self-worth. How happy are you with who you are? Do you feel that you deserve good things? Do you believe you’re a good person? There are several measures of self-esteem, and it’s one of the biggest areas of study in recent years.

You mean, I think, Does the concept of self-esteem have validity, does it describe an actual personal characteristic?
The answer is yes.
It means that a person has a generally good and healthy opinion of herself, confidence in herself, likes herself. That does not mean arrogance, necessarily, or having a superiority complex. But it does mean not having an inferiority complex, probably.

It’s a catchphrase combining all you’ve described individually.

Self-esteem is your appraisal, your evaluation and your feelings about yourself. Your opinion of the person who you have been living with since you were born: Yourself.
Nathaniel Branden – who is considered the father of the self-esteem movement – states that;
"Self-esteem is the experience that we are appropriate to life and to the requirements of life. More specifically, self-esteem is…
1.Confidence in our ability to think and to cope with the basic challenges of life.
2.Confidence in our right to be happy, the feeling of being worthy, deserving, entitled to assert our needs and wants and to enjoy the fruits of our efforts."
You have high self-esteem when you feel good, happy, satisfied about yourself. When you think you are capable of achieving anything. When you have lots of energy, when you are focused, confident and persistent to visit success anytime.
You have low self-esteem when you don’t feel good about yourself. When you think you are not worth of even trying to move forward. When you are focusing on your weaknesses instead of paying attention to your strengths.
Self-esteem is your control, your approach toward the “attacks” of reality.
You are the only person on the planet who can establish, build and nurture your self-esteem. You are the only one who is in charge of creating a prosperous, happy life and to take control over your actions, decisions and emotions in your life.
That’s what self-esteem is all about.
I hope that I could answer the question properly.
