I think you will have to want to raise your self-esteem in order to be successful doing it. It's very sad that you are satisfied with a low opinion of yourself. Everyone should do whatever they can to improve themselves. The opinion you have of yourself is the same one you are projecting out to others when they meet and form an opinion of you. It will not help you get or keep a good job or a great relationship. I suggest you try some counseling in order to help you feel better about yourself. You deserve to love the person you are and can be.
