     Many people think sports are just for winning and honor, but there is a lot more you can gain from (get

out of) them. I have learned over the past years that sometimes when I lose, I get a lot more out of it than

winning. Also, I find a lot of times in sports, people are getting too caught up in the game instead of just having

fun. The real purpose of sports is to have fun and learn life lessons along the way.

     I greatly encourage you to be a part of the school sports. Even if you are not the best, you can still have

fun. Sports give people a great and healthy way of spending an afternoon, instead of lying around playing video

games or even getting into bad things. Sports also give us a sense of achievement. There isn't a better feeling

than to have done something fun and productive for my day.

     I think that we all need sports to give us courage. If we try hard in sports, we usually do well. If we did

the same in study, we would all be champions. Another reason why I encourage you to play sports is that it's

just fun. Without sports, our lives would just be boring. So as you may be able to tell, sports are amazing!

     Our coaches not only teach us to play sports, but show class and good sportsmanship while playing them.

It's never fun when you lose to have the competitor rub it in your face. That's why our coaches teach us to

show class when we lose; also, when coaches get onto you, don't get down. They only want to see you

improve and learn from what they say. When you do badly and they don't shout loudly is when you should

start worrying because they are giving up on you.

    Overall, sports are great! They bring out the best and worst of a lot of us. However, we can't let sports get

too serious to where it brings down all the fun. So to have the most fun in sports, you just need try your best

and not worry so much about the winning or losing.
