Why I have low self esteem?

try focusing less on yourself and more on others if you put your energy into helping other beings and being genuinely compassionate one day you look at yourself and remember that you used to worry about this helping others is very fulfilling and its an excellent distraction from yourself and lets be honest you are the only one who can really give your self any kind of feeling that's why they call it SELF esteem.

Try to act confident and maybe u will get better at it. Thats what i do.

There could be many reasons why you feel that your self-esteem is low. Usually the answers will come from you as to why that is the case. Some examples of low self-esteem include not being appreciated by those you want to appreciate you; not having certain skills you would like to have; dissatisfaction with your relationships; dissatisfaction with your financial situation, or job potential, etc. You get the idea. You will have to ask yourself the specific questions as to what is missing in your life right now, or what is in your life that you'd rather not have. Basically, to be confident and have excellent self-esteem, you need balance between several very important components in your life. These components are health, family, friends, career, spiritual, and financial. Many of my self-confidence clients confuse career with financial. It is not the same thing. For example, you may have chosen a career that you love with a job that doesn't necessarily pay great, but you just love your job and are happy with it. On the financial side, you may have learned to manage your money in such a way that you are able to keep enough on a monthly basis to invest wisely and make it grow exponentially. Does this make sense?
So if you examine the components of your life and just make a brief analysis for yourself, find which aspect needs the most work and simply make a plan. Since each human being is a work in progress, each and everyone of us has something to improve on in every aspect of life. The trick is to be honest with yourself and just take into account what is already going well and what needs some work. Then learn about ways to polish what needs polishing. Meet likeminded people, take a class, hire a coach, read some practical literature in that area. Are you working too hard and feel you need some cool hobby? You know the answers already. All you need to do is ask yourself the right questions. Then take action.

aboutfm2010, you are posting the exact same content for several topics.

Don't focus on building an identity.
You are who you are, and who you are is great. I think you might be not only hiding your self-esteem but you might be suppressing your own personality. Show people who you are and remember not to look for validation from them. If you amuse yourself and make yourself happy than you will also amuse other people and they will see you for who you are.
The reason why you think some people don't like you is that those people probably just don't know you, who you really are. Don't be afraid to show them, and you can even fake it until you make it. Be aware of when you feel shy, then just let loose and force yourself to do what you might be too shy to do in public and would actually do with really close friends or family.

Always anticipate that people will like you, if you really believe it than it will come true because your mind and body will make the adjustments necessary with that confidence to make it reality.
Also, do not depend on the outcome of any situation, don't be thinking, wanting and wishing for people to give you a good response to anything you do. Just believe wholeheartedly in yourself and you'll have the power.

You are too self-aware and that's why you have low self-esteem. Try to focus outward instead of on yourself. The funny thing is that people will like you if you are genuinely interested in them and give them attention. You'll only have to talk to them and by doing so you are not so focused on yourself.
