看着蜗牛在阳台上缓缓爬过，我的视线就被它吸引住了。不是因为讨厌它，而是对它身后那条长长的线产生了兴趣。我不清楚小小的蜗牛要到哪儿去，但它分泌的黏液却告诉我它已经到过了这里。这是它留下的痕迹，对于它，我的心里竟产生了一丝敬佩。
我在学习的道路上缓缓前进着，我知道前方困难随处可见，讨厌的绊脚石也会越来越多。身边的朋友已经没有时间再来帮助我了，我只拥有一份信念，打挎一切困难，努力达到终点的信念。我要将我的脚印留在探究的路上。
蜗牛已爬过了阳台，它正在向屋顶出发。缓慢的它显得更慢了，小心翼翼地，勇敢地向上爬行，它身后的痕迹依旧存在，让人联想到了它前进的艰辛。我很想帮它一把，刚想伸出手却又不由自主地停住了，脑中蹦出了一个想法：如果没有经历艰难的过程，胜利的终点对它又有什么意义呢？
我沉寂在一片题海中，想空闲一下，手中的笔却迟迟不肯放下。休息之余，想到两点一线的生活，想到堆积如山的作业，心中一阵乏闷，怪自己太笨，不懂得复制别人的作业，让自己轻松一下，可这个念头才一出世，就被理智给抹了。是啊！我要的是成绩，并不是那纸上的大答案。
夕阳西下，柔和的金色光芒洒满了大地，白的.墙也变成了金色。小小的蜗牛还在努力地向上爬着。我几乎已经不能找到那小小的一点了。但我知道，它一定会到达屋顶的。它身后那条长长的痕迹见证了它的努了力，也让我明白了，路是一步一步走出的。
蜗牛如我，在不懈地努力着。我似蜗牛，为小小的梦不断拼搏着！蜗牛告诉我，当你在梦想的途中脚踏实地留下属于自己的痕迹，未来才能绽放光彩！

“天生我材必有用”，每一个人一出生在这个世界上，都是一位人才。有的人不是天才，但却努力的.工作和付出；有的人是天才，但却又好吃懒做；但有些人是天才，又愿意努力的付出，就又更上一层楼了。
但人的成就表现是单靠天生才能做到的吗?像从小就不是天才的爱迪生，长大却是一位发明家，为什么呢?绝对不是天神看好他，而是他努力不懈。从小到大，遭受到许多挫折的他，却从来没放弃过，因为他拥有恒心毅力、锲而不舍的精神。
天 才好比是良田，努力好比是农夫，唯有肯下功夫，用心耕耘，时时刻刻努力，才能有丰硕的收获。要得到“努力”，就一定会经历过许多的失败与挫折，但唯有恒心毅力、锲而不舍、永不放弃的精神，才能克服挫折与失败。做每一件事情都要努力，才会有成果。努力胜过了天才，唯有“努力”，才会有“天才”!
