Without the rain, there would never be rainbows.
There are many things in this world belong to a relative concept,
big and small, long and short, happy and sad, ups and downs;
And these are exactly the moments we go through that
makes up the whole life we live. Life is like a piano.
The white keys represent happiness and the black shows sadness.
But as you go through life journey, remember that the black keys also make music.
You won’t feel happy if you have never experienced what makes you unhappy.
如果没有雨，永远不会有彩虹。这个世界上有很多事物处在一个相对的概念里，大与小，长与短，快乐与悲伤，起起和落落；而恰恰是我们所经历的这些时刻，构成了我们生活的全部。生活就像一架钢琴，白色键代表快乐，黑色键代表悲伤，而在你的人生旅途中，莫忘记：黑色键亦能弹奏出旋律。如果不经历些不开心的事情，我们更不会感知到幸福。
只有和不幸的对比，我们才会醒悟：哪怕是简单平凡都是一种幸福。不是吗？希望你喜欢今天的能量站，无论你快乐还是悲伤， remember that black keys also make music.
