Many strive deliberately for so-called happiness; some achieve it, but at a tremendous cost. Many philosophers say that happiness is a feeling. The sense of happiness diminishes with the level of satisfaction and is closely tied to one's mindset.

但不是快乐的人就没有悲伤的，就像翠竹总要开花，凋折，而四季也总有萌蘖和落叶的时节。只是我把悲伤淡淡地抹在心底，在别人看不见的日子里，把它淡淡地忆起，再淡淡地忘却。平淡的日子最美，平淡的日子最真。只要人甘于平淡，快乐就很容易。
