Think of life as a game in which you are playing with five balls in the air. You name them work, family, health, friends and spirit and you keep all of them in the air. You will soon understand that work is a rubber ball. If you drop it, it will bounce (弹跳) back.

But the other four balls, family, health, friends and spirit, are made of glass. If you drop one of these, they will be broken. They will never be the same. You must understand that and try to have balance in your life. How?

Don’t look down on your worth by comparing yourself with others. It is because we are different and each of us is special.

Don’t let other people set goal for you. Only you know what is best for yourself.

Don’t give up when you still have something to give. Nothing is really over until the moment you stop trying.

Don’t be afraid of difficulties. It is by taking chances that we learn how to be brave.

Don’t shut love out of your life by saying it’s impossible. The quickest way to receive love is to give it; the fastest way to lose love is to hold it too tightly; the best way to keep love is to give it wings（翅膀).

Don’t run through life so fast that you forget not only where you’ve been, but also where you are going.

Don’t be afraid to learn. Knowledge is a treasure you can always carry easily.

Don’t use time or words carelessly. You can’t get them back. Yesterday is history, tomorrow is a mystery, and today is a gift; that’s why we call it “the present”. Life is not a competition, but a trip, step by step.

Flying out of an airport in the United States is not always easy. You will need to complete the ticketing process, baggage check, and security clearance procedures before boarding the plane.

If you are flying on an international flight, you'd better arrive two hours before your plane is scheduled to leave. You might need more time in a busy airport in a large city. If you are traveling on a domestic (国内的) flight, you may only need to arrive at the airport 90 minutes before your plane takes off.

Every airport in the States is now moving its ticketing procedure to electronic ticketing device. By using a ticketing machine, you have the chance to choose a seat you like on the plane. If you use it to check-in your bags, you will only have to talk to the ticketing agent when you turn in your luggage to be tagged (加标签). At the same time a real person will be nearby to help you if you need it.

After you have checked in, you will have to pass through airport security. Have your ID card or passport and boarding pass ready to show the security officer when entering the security checkpoint line. Airport security is getting tight in the States today. You're not allowed to travel with any prohibited things like knifes or fireworks.

After the security staff has checked your travel documents, you shall put all of your belongings through a scanning machine and then walk through a metal detector (探测器) or a full body scanner. You need to take off your coat, belt, and sometimes your shoes to go through one of these scanners. Be sure not to have any metal in your pockets. If you do not understand a question you are asked at a security checkpoint, ask the person to repeat their question until you are able to respond with an accurate answer.
