     Think back to when you did something new for the first time. Self-confidence isn't always what we think it is. Many experts say that self-confidence and self-esteem are different. Self-confidence is about what we can do by virtue of our efforts. It grows along with the quality of the effort.
     Self-esteem is more fundamental (基本的)and is about the feeling of being worth something, just because we are who we are, and not because we have done something. A good sportsman can have a huge success and self-confidence, because he's good at his sport. In the same time his self-esteem can be low, if his parents have never recognized and treasured him for the person he is deep inside, but only for his performances in sports.
     Build self-esteem if you were not born with it. Some people just have it, as if they were born with it. They talk in front of a crowd of people, sell themselves at job interviews or start an interesting conversation with people they've never met before.
     Self-confidence isn't something you receive as a birth gift. It's something you develop gradually as you turn over the pages of the thick book of life. If you work goal-directed to improve your belief in yourself, you'll eventually build up your courage to do what self-assured (自信的) people find natural, instead of developing pounding hearts, breathing difficulties and trembling hands.
     Regardless of fear and shyness you'll have to get out of your hiding to improve your self-confidence. Be more visible to your surroundings. Do something else than you used to. Try yourself in different situations. We all have many great abilities that just have to be exposed.
