These days,with the rapid development of the economy,the average quality of living conditions is greatly improved.When there's nothing to worry about housing,necessaries for life,and heating during winters,people begin to pay attention to their behaviors.As for me,self-image is very important for individuals.Even for organizations,a good general image will benefit a lot.Therefore, I strongly believe that we should choose to be polite. 
To be specific,being polite is very useful and convenient in most cases.Because being friendly with others is actually an important part of our culture.If the majority of citizens can keep themselves from being rude,the whole country will show up a good mental outlook to the world.I still remember several years ago,when it's China's turn to hold the Olympic Games,the government put programs of teaching how to be polite as the first things to do.Even in our capital city,impolite behaviors such as spit around or talking loudly in public occasions are still very common.Fortunately,the training are effective enough,and our people are active to change their bad manners,We present a very good impression to both the foreign athletes and the tourists.
Most of us have been taught to be polite since we were children,for good manners would help  improve the efficiency while we are working or studying.Being polite to others would create a harmonious atmosphere.And having a good mood usually leads to perfect cooperation and interaction and so as to increase the team spirit.In fact,being polite will never be emphasized too much.Many corporations are running well because of treating rite training seriously.Although such spiritual training doesn't create concrete benefits,it favors the survival of those companies in the long run.That's because the public are prone to trust those companies with polite workers.And companies characterized by politeness are more likely to defeat their rivals.
I have to admit that sometimes being rude is a way to protect ourselves from being hurt.There is no use to be polite with a killer or a robber.They are dangerous and merciless.It is inevitable to be rude when people are fighting for their rights or trying to save their family members' lives.However I still agree with treating those crimes fairly and give them a chance to rebuild themselves when they are in prison doing their time.I believe humans virtue would eventually influence the lost souls successfully.
In sum,due to the tremendous amount of advantages bein brought by politeness and good manners,I am strongly determined to choose to be polite.With politeness,I am sure that our life in the future will full of happiness.
