If you were one drop of water, would you moisten the field? If you were a ray of sunshine, would you brighten the darkness? If you were a morsel of food, would you provide others with nutrition?If you were the tiniest bolt, would you stay in place and fulfill your duty? If you want to tell others your ideals, do you preach them day and night? When you are alive do you always remember to work hard for the future lives and let the world become more beautiful day by day? I want to ask you: what do you contribute to the future? In life you must be a giver and not just a taker.
