    Speak loud

    When you are not confident, you can't do well what you want to do. You speak in a voice so low that other people can hardly hear you. Try to speak loud enough so that people can hear you clearly. The high voice can help you become more confident.

    Play sports 

    Physical exercise makes you tired but completely relaxed. Astrong body helps you be full of confidence.

    Encourage(鼓励) yourself

    Write down a list(目录) of things you did during the day to see how many things you have done well. Did you finish your homework? Did you tell a joke that made everybody laugh? Give yourself praise for the good things you've done.

    Get rid of fear

    Fear(恐惧) comes along with failure(失败). But it's easy to overcome (克服) if you know that failure is part of your life. Don't hide your head just because you said something stupid last time. Try to start again and believe you can do better.

    Pick up a hobby

    If you like singing, sing as much as you can.  In some ways, a hobby can make you outstanding(杰出的). And it will make you happy and confident.
