..... If you were a drop of water, would you moisten an inch of land? If you were a ray of sunshine, would you light up a little darkness? If you are a grain, have you ever given birth to useful life? If you were the smallest screw, would you stay in your life forever? If you want to tell us something, are you preaching the best ideals day and night? Since you are alive, do you work hard for the future human life and make the world better day by day? I want to ask you, what does it bring to the future? In the warehouse of life, we should not just be endless givers.
