I’d modify this “ชีวิตนี้สั้นนัก จะทำอะไรก็รีบทำ” to “ชีวิตที่เหลือนี้สั้นนัก จะทำอะไรก็รีบทำ”. Don’t let hopelessness and despair (from failures) become a drag on our life. We are still capable of achieving many great things, giving many great things and enjoying our happy moments.
Life may slow down so we have more time to think carefully and to do things more excellently. ;-)
Give a smile.
