看着这个我从小学五年级开始喜欢的男孩
算是我的大半个青春
当他那个时候慢慢淡出时，我也没有那么疯狂了，在这个时候我也喜欢上了很多其他的明星
但是，没有一个能像他一样对我意义那么深那么喜欢
在我心里，没有一个人能比的上他[心]
You are my only one
I only have one life，and I only wanna live it with you[心]@JustinBieber

It is not difficult to imagine a world short of ambition. It would probably be a kinder world: with out demands, without abrasions, without disappointments. People would have time for reflection. Such work as they did would not be for themselves but for the collectivity. Competition would never enter in. conflict would be eliminated, tension become a thing of the past. The stress of creation would be at an end. Art would no longer be troubling, but purely celebratory in its functions. Longevity would be increased, for fewer people would die of heart attack or stroke caused by tumultuous endeavor. Anxiety would be extinct. Time would stretch on and on, with ambition long departed from the human heart.
