Some things are more precious because they don't last long.
有些东西之所以弥足珍贵，是因为它们总是昙花一现。
Life is ephemeral, so it is very precious.
Time is limited, so every second counts.
If you love a flower on a star, it is sweet at night to gaze at the sky.
如果你爱上一颗星星上的一朵花，那么，夜晚仰望星空就是一件很开心的事情。
From The Little Prince.
If you love something sincerely, you wouldn't feel tired to make it perfect.
Don't wait. Don't feel fearful. Don't grieve at the past misfortune.
