    I was at my parent's dinner table. Before me was a worn journal of thin and discolored pages. It was my grandfather's journal and now belonged to my father. My grandfather had passed away in the months leading up to my birth. I never got to visit the places he had frequently and people who had been a part of his life's journey.

    I was now about to enter his world, through the words he had left behind. Within minutes, I was attracted by the power of the written words. In the magical script before me, I was transported to another age when food was an everyday art, planned, prepared and enjoyed in the company of others, and a time when people had the heart to pause，their own lives to embrace (拥抱）each other's struggles. All this was conveyed to me in the beauty of the words that flowed together to connect with the writer's mind and understand the world they lived in.

    That kind of writing seems to be lost on us today. We have gotten used to writing in bite-sized pieces for a public looking for entertainment, and hungry for information. No wonder, there are nearly 200 million bloggers on the Internet and a new blog is created somewhere in the world every half a second. Instead of adding to our collective wisdom, most of these writings reflect the superficiality (肤浅)and impatience of our day and age.

    This not only robs us of the skill of writing impressive essays, it also prevents us from exploring what is truly important. Writing humbles us in a way that is vital for our character growth, by reminding us about the limits of the self and our appropriate place in the vast flow of life. Writing frees us by helping us explore the unknown so that we truly open up to the magic of the world around us. I saw all of this in the writing s of my grandfather. And I've seen it again and again in the writings of the greatest thinkers of humanity. Their writings reflect deep thought on issues of human importance.

请回答如下问题：

“成”与“功”

    失败者对于成功，一方面是羡慕不已，另一方面是急躁不安，巴不得一口吃成个大胖子。殊不知成功是由__成__与__功__两个字组成的成是功的积累叫做__功到自然成__。

    晋代大书法家王羲之，20年临池学书，洗笔把池水都染成黑色了，才有在书法上炉火纯青的造诣。功是成的基础，一个人要想取得成功，必须要经过艰苦的奋斗，这个过程也就是功的积累过程。

    一滴水从檐楣上掉下来，重重地落在石头上，“啪”的一声炸出一朵水花，可是石头上看不到丝毫的痕迹。然而，经过一年、两年……坚硬的石头终于被水滴滴穿。

    如果成功很容易，无需奋斗就能达到的话，如果成功不是需要功的积累，不需要努力攀登的话，那成功就会变得廉价，成功就失去了它原有的耀人的色泽，那我们还要成功干吗？

    李时珍跋山涉水，遍尝百草，数十年如一日地收集整理，笔耕不息，才有药学巨著《本草纲目》的问世；司马迁游历各山大川，博览经典秘籍，遭受宫刑，忍辱负重，笔耕不辍，才有《史记》的诞生。

    在走向成功的路上，既无捷径，也没有宝葫芦，所以与其坐着羡慕别人“成”，倒不如站起来积累自己的“功”。须知，任何一朵鲜花的盛开，都需要花苞长期孕育；任何一枚勋章都要成功者付出相应的代价。成功是自私的，它绝不会将辉煌施舍给懒汉，成功又是公平的，它会毫不保留地将满天的灿烂星光照在坚持不懈的奋斗者身上。
