I have been thirsting for a pair of new shoe all along until I saw some people who had lost their feet.

There`s a story :A person is ill in bed many years and now he is dying. Doctor tells him and his family member, his life will not be long. Hopeless he only can lies down on the bed prays to God: "God please let me live!" He has really lived for several years. This caused his prayer to be more diligent, and prayed the content also changed: "God, please let me go down for a walk!" When he can walk then he starts to change the prayer word: "God, please let me obtain a sum of money......" . Desire without limits, is not joyful all because is not content. Said has a person, she feel regret and unsatisfied because she doesn`t have a new pair of attractive shoes. One day, when she saw someone with no feet, he will be no longer feel unsatisfied because of no having a new shoes. So, always thank God of what you have now, don`t ask for more and more. 

有个故事说：一个人卧病在床多年，行将就木。医生告诉他和他的家人，他去日无多了。无望的他只能双手合十，十分虔诚地躺在床上向上帝祷告：“上帝啊请让我活下去吧！”果然，他活了几年。这使他的祷告更勤快了，并且祷告的内容也改为：“上帝啊，请让我下地走走吧！”当他可以下地乱走时，他又开始改祷告词：“上帝啊，请让我得到一笔钱吧......”。欲望无止境，不快乐都因为不知足。说是有一个人，他一直为自己没有一双漂亮的鞋而遗憾。一天，当他看到一个没有双腿的人时，他就不再为没有鞋子感到遗憾了。

俗話「知足常樂」就告訴了我們：感覺心安就是享受豐富的精神生活。
The saying "Happiness lies in contentment," tells us that feeling at ease is enjoying rich spiritual life.
