Life isn't an MP3 where you can play what you want. Life is a radio where you have to enjoy what's being played. 生活不是mp3,不可能任由你播放喜歡的歌,它只是一台收音機,你只能享受它為你播放的每一首歌。
The reason so many people find it so hard to be happy is that they will always see the past better than it was, the present worse than it is, and the future less resolved than it will be.
