Many suffer from shyness. In order to give other people a chance to know more about you, you need to get over it. Then how to control shyness?
    First, make decisions not to hold back in conversations. What you have to say is just as important as what other people say. And don’t turn down party invitations just because of your shyness.
    Second, prepare yourself for being with others in groups. Make a list of the good qualities you have. Then make a list of ideas, experiences, and skills you would like to share with other people. Think about what you would like to say in advance. Then say it.
    Third, if you start feeling self-conscious in a group, take a deep breath and focus your attention on other people. Remember, you are not alone. Other people are concerned about the impression they are making, too. Don’t be afraid to speak up and give your point of view. Moreover, remember everyone experiences failures and disappointments. Regard them as lessons instead of frustrations.
    As each of us is an individual, we behave in our own personal ways. No one gets over being shy completely, but most people do learn to live with their shyness. Even entertainers admit that they often feel shy. They work at fighting their shy feelings so they can face the cameras and the public.
