In my early childhood, my parents and teachers taught me to be persistent (执着) in every task I devoted myself to. I was   ____  that persistence is the only way towards success. But a small   ____  made me change my mind. One day my two­year­old son,   ___   at a dozen of “stood” color marker­pens, cheered excitedly，“Mummy, look! I did it.” Afterwards, he collected some ball­pens,   ____  to do the same. Hard though he tried, the ball­pens just lay  ____. He turned to me for help. Noticing they had either sharp or round ends, I said   ____， “Mummy can't help you.” To my surprise, he wouldn't listen and continued trying... I was dumbfounded by his persistence. My son's behaviour reminded me of George who was always   ____  in his work and rarely talked to anyone. To him,   ____， there was no such thing called weekends or holidays. Our boss praised   __  about him and   ___  us to look up to him as a role model. One day I met George. “Gonna work late again tonight？” “Probably can't leave till midnight，” he said. “How many hours have you put in here each week, eighty or ninety？” “____.” “Don't you have time to be with your family at all？” He shook his head slowly and   ____  a sigh. “It's not what I wanted. But I have worked on it for so long. It's much too  ____  to even think about letting go.” A year later I resigned. The  ____  thing I heard about him was that his wife divorced him. Since then I've never seen him. But occasionally his aged   ____  would come to my mind. Until that day,  ____  knowing why the ball­pens couldn't stand up, the two­year­old had   ____  the impossibility after many failures. He put aside all the ball­pens and kept only those water markers for his “game”.   ___， he already learned to let go of his previous   ____ attempts.
