Shyness is a kind of fear. People who are shy always worry too much about what people think of them or embarrassing(使尴尬) themselves in some way in front of others. How can we overcome shyness?
1. Have a good posture(姿势)
The way a person holds himself/ herself says a lot about that person. People with sloped(倾斜的) shoulders don't think of themselves as important. So stand up straight, put your shoulders back, keep your head up, and always make eye contact(接触). By practicing good posture, you will feel you have the ability to do things well.
2. Increase your walking speed
You can tell if a person is confident (自信的) by the way he/ she walks. People who walk in a slow way, and look at the ground while they walk usually have no confidence in themselves. However, people who have confidence in themselves walk faster. That is because they have important things to do, friends to meet, places to go, etc. So walk a little faster, keep your head up, and look straight ahead.
3. Do some exercise
Exercise increases your energy levels in the body. That will put you in a more positive(积极的) state of mind. By doing exercise, you will feel sure of yourself. Think about it; it is better to do some exercise than just watching TV all day.
4. Do things that make you feel good about yourself
This can be anything that you really like doing like going to the theater, listening to music, traveling, helping someone out of a problem, etc.
