Sometimes people have low self-esteem because they do an action that they themselves consider wrong or unhealthy. Sticking to your moral and ethical codes in everyday life will help you build self-esteem and confidence.

If you're just talking to your family or friends, it's sharing with those you love. And chances are that if you want to feel good about yourself, then you're have a lot to tell others about your accomplishments. When your friend says,"I liked your presentation," try to avoid brushing her off with "I was so nervous, I forgot a whole slide!." Just say "Thanks," and let the words sink in. If you're self-deprecating or put yourself down any time people try to make you feel good, then they may avoid doing it in the future. Instead, the next time you hear something nice about yourself, look and feel legitimately happy to hear it instead of fighting it.  Look the person in the eye and thank her like you really mean it. If the compliment makes you uncomfortable, you do not have to accept it. However, if you like the compliment, accept it. For some people, putting in real time and care into their hygiene will make them feel that they are worth taking care of. Taking care of your body is just as important as taking care of your mind, and many extreme forms of hygiene are also relaxing.  Examples include taking a long bath or pampering your skin with great-smelling soap or lotion. This is different from throwing on a lot of makeup or buying trendy outfits. This means seeing that your body should be given time and care. You know which shirt makes you feel...
