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.

    吕元膺,字景夫,郓州东平人。姿仪瑰秀,有器识。历右司员外郎。出为蕲州刺史,尝录囚,囚或白:“父母在,明日岁旦不得省,为恨。”因泣,元膺恻然,悉释械归之,而戒还期。吏白“不可”,答曰:“吾以信待人,人岂我违?”如期而至。自是群盗感愧,悉避境去。

    元和中,累擢给事中。俄为同州刺史。既谢,帝逮问政事,所对详诣。明日,谓宰相曰:“元膺直气谠言,宜留左右,奈何出之?”李藩、裴垍谢,因言:“陛下及此,乃宗社无疆之休。臣等昧死,请留元膺给事左右。”未几,兼皇太子侍读,进御史中丞。拜鄂岳观察使。尝夜登城守者不许左右曰中丞也对曰夜不可辨乃还明日擢守者为大将。

    江西裴堪按虔州刺史李将顺受赇,不覆讯而贬。元膺曰:“观察使奏部刺史,不加覆,虽当诛,犹不可为天下法。”请遣御史按问,宰相不能夺。选拜东都留守。故事,留守赐旗甲,至元膺不给。或上言:“用兵讨淮西,东都近贼,损其仪,沮威望,请比华、汝、寿三州。”帝不听,并三州罢之。留守不赐旗甲,自此始。都有李师道留邸,邸兵与山棚谋窃发,事觉,元膺禽破之。始,盗发,都人震恐,守兵弱不足恃,元膺坐城门指纵部分,意气闲舒,人赖以安。东畿西南通邓、虢,川谷旷深,多麋鹿,人业射猎而不事农,迁徙无常,皆趟悍善斗,号曰“山棚”。权德舆居守,将羁縻之,未克。至是,元膺募为山河子弟,使卫宫城,诏可。

    改河中节度使。时方镇多姑息,独元膺秉正自将,监军及中人往者,无不严惮。入拜吏部侍郎。正色立朝,有台宰望,处事裁宜,人服其有体。以疾改太子宾客。居官始终无訾缺。卒,年七十二,赠吏部尚书。
