阅读下面短文，根据第1至第3小题的具体要求，简要回答问题

     What are the situations that make you shy? You're not shy all the time. For example, when you're with your best friend, you're probably very open and comfortable being yourself. Shyness is the effect of feeling insecure(不安全). If you can identify what you're feeling insecure about, you can then take action on it.

     Many of us tend to focus on what we're not good at, rather than recognize what we are good at. As a

result, we feel awkward around others, because we feel there's nothing impressive about ourselves. It's

time to stop selling yourself short and start focusing on your strengths. What are you good at? What are

your past achievements? What are things you've done that you are really proud of? Spend some time to

recognize them.

     Many people worry too much about what others think about them. But the funny thing is, it's just in

your mind. Most people are actually too busy to pay attention to what you're doing or not doing, so stop

spending time worrying about others' opinion of you.

     Can you think of someone (whether a friend or a famous person) you know who is very confident,

assured and outgoing? Use the person as your role model. Whenever you feel shy, ask yourself what that

person will do/say in this situation. Then, do that. Soon, it becomes second nature to you to behave in that manner.

     Another great way to overcome shyness is to observe how others around you act. Reduce the time

you spend worrying about what others think of you and look outward at how others behave themselves

socially. What do they say? How do they act? What can you learn from them?
