     There are only two reasons people cannot achieve their goals: The goals aren't important to them; or

people don't break them into small enough pieces. So all we need to do is to try our best...

     Have you ever watched a quitter in a boxing match-a man who just gives up and walks away? The

whole crowd boos. They throw drink bottles and bits of hot dog into the ring. They don't throw things

because he lost. They throw things because he quit. In our hearts we all believe that we should do our

best.

     Eric Moussambani swam for Equatorial Guinea (赤道几内亚) at the 2000 Olympics. This was the

first time Eric had swum a 100-metre race. He swam with his head out of the water and he barely kicked

his legs. In the first lap he was really struggling (挣扎). In the second he was nearly drowning (沉没).

But Eric was fighting with everything he had.

     At the turn, the large audience began to shout and with every stroke (划水) the noise got louder and

louder. Twenty meters from the finish, Eric was hardly moving but the crowd was crazy. When he finally

hit the wall, the cheering and stamping all but lifted the roof off the stadium. His time of 1 minute 52

seconds was about a minute slower than all the other competitors. Who cared? Eric Moussambani had

done his best.

     When you make an honest effort, people support you. You feel happier when you do your best. Think

about what it feels like walking to school on those days when you have done all of your homework and

done it as well as you can. Don't you feel just a bit more interested about school? Why? Because you are

always happier when you make a 100 percent effort, whether it's for an essay or a basketball game.

     Your teachers will tell you"Work hard!" and your parents will probably tell you "Work hard." But you

don't work hard to please your parents and teachers. The big reason you do it is for you. If you get good

marks, that's a prize. If other people notice, wonderful! But the main reason is how you feel about yourself.

     Even when you do your best, it is not certain that you will succeed. You may do your best, and still

be criticized. You may do your best, and still have people laugh at you. But when you do your best, the

reward is that feeling that says, "I did everything I could."
