Do not be anxious about tomorrow, for tomorrow will be anxious for itself. Let the day's own trouble be sufficient for the day.

Do not be anxious about tomorrow, for tomorrow will be anxious for itself. Let the day's own trouble be sufficient for the day.

不要为明天忧虑，因为明天自有明天的忧虑。让这一天的烦恼足以支撑这一天。

-- Samuel Butler 塞缪尔巴特勒
