Why should I do my best
There are only two reasons people cannt achieve their goals:The goals weren't improtant to them;people didn't break them into small enough pieces.So all we need is to try our best...

*Why should I do my best
Have you ever watched a quitter in a boxing match-a guy who just gives up and walks away.The whole crowd boos.They hurl drink bottles and bits of hot dog into the ring.
They don't throw stuff because he lost.They throw stuff because he quit.In our hearts we all believe that we should give our best.
Eric Moussambani swam for Equatorial Guinea at the 2000 Olympics.He didn't win.Eric had never ever seen a 50-metre pool.At home he trains in a little hotel pool-when there an no guests.
The two other competitors in his 100-metre heat-from Niger and Tajikistan-were both disqualified for false starts,so he swam alone against the clock.
This was also the first time Eric had swum a 100-metre race-something the crowd soon suspected.He swam with his head out of the water and he barely kicked his legs.
In the first lap he was really struggling.In the second he was nearly drowning!But Eric was fighting with everything he had.
At the turn, 17500 spectators began to roar and with every stroke the noise got louder and louder.Twenty metres from the finish,Eric was barely moving but the crowd was going bananas.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 give an honest effort, people support you .

*You feel happier when you do your best
Remember 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 enthusiastic about school? Why? Because you are awalys happier wehn you give 100 percent,whether it's an essay or whether it's a basketball game.
Your teachers will tell you "Work hard!" and your parents will probably tell you "Work hard!" One day your boss will tell you "Work hard!" But you don't work hard to please parents and teachers, and you don't work hard to keep your boss off your back.
The big reason you do it is for you.
If you get good marks,that's a bonus .If other people notice,wonderful!But the main reason is how you feel about yourself.

*Sometimes you give everything you've got...and still fail!
It's not failing that hurts so much.It's that feeling that you didn't do all you could.
Even when you do your best ,there are no guarantees that you will succeed.You may do your best, and still be criticised.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."

*And if you have done all you can...
There comes a point when you say to yourself,"That's enough."If you are facing an examination,or an impartant interview,and you have prepared as well as you can, you then let go .You walk into the examination room,or the interview, and say to yourself,"I have done everything I can-I'll accept whatever happens."

beautiful essay......

if you put your heart into sth.and try your best to do it.whatever the result is,you won't feel regret.cause you've tried your best.......
