知足常樂   
                                        這道理人人懂
                                        但似乎人人都不快樂

                                        只因
                                        貪婪    是人的原罪
                                        慾望    則是它忠實的幫兇
                                      
                                        他們聯手剽竊著我們的快樂
                                       
                                        貪婪既出    便無法知足
                                        慾望加持    人愈發貪婪

                                        以至於
                                        渴求越來越大
                                        煩惱越來越多
                                        快樂也就越來越少
