If I were a boy again, I would practice perseverance more often, and never give up a thing because it was or inconvenient. If we want light, we must conquer darkness. Perseverance can sometimes equal genius in its results. “There are only two creatures,” syas a proverb, “who can surmount the pyramids—the eagle and the snail.” If I were a boy again, I would school myself into a habit of attention; I would let nothing come between me and the subject in hand. I would remember that a good skater never tries to skate in two directions at once. The habit of attention becomes part of our life, if we begain early enough. I often hear grown up people say “ I could not fix my attention on the sermon or book, although I wished to do so” , and the reason is, the habit was not formed in youth. If I were to live my life over again, I would pay more attention to the cultivation of the memory. I would strengthen that faculty by every possible means, and on every possible occasion. It takes a little hard work at first to remember things accurately; but memory soon helps itself, and gives very little trouble. It only needs early cultivation to become a power.
假如我又回到了童年，我做事要更有毅力，决不因为事情艰难或者麻烦而撒手不干，我们要光明，就得征服黑暗。毅力在效果上有时能同天才相比。俗话说：“能登上金字塔的生物，只有两种——鹰和蜗牛。”假如我又回到了童年，我就要养成专心致志的习惯；有事在手，就决不让任何东西让我分心。我要牢记：优秀的滑冰手从不试图同时滑向两个不同的方向。如果及早养成这种专心致志的习惯，它将成为我们生命的一部分。我常听成年人说：“虽然我希望能集中注意听牧师讲道或读书，但往往做不到。”而原因就是年轻时没有养成这种习惯。假如我现在能重新开始我的生命，我就要更注意记忆力的培养。我要采取一切可能的办法，并且在一切可能的场合，增强记忆力。要正确无误地记住一些东西，在开始阶段的确要作出一番小小的努力；但要不了多久，记忆力本身就会起作用，使记忆成为轻而易举的事，只需及早培养，记忆自会成为一种才能。
Whether sixty or sixteen, there is in every human being's heart the lure of
wonders, the unfailing childlike appetite of what's next and the joy of the game
of living. In the center of your heart and my heart there is a wireless station:
so long as it receives messages of beauty, hope, cheer, courage and power from
men and from the infinite, so long are you young.
无论是60岁还是16岁，你需要保持永不衰竭的好奇心、永不熄灭的孩提般求知的渴望和追求事业成功的欢乐与热情。在你我的心底，有一座无线电台，它能在多长时间里接收到人间万物传递来的美好、希望、欢乐、鼓舞和力量的信息，你就会年轻多长时间。
An individual human existence should be like a river—small at first, narrowly
contained within its banks, and rushing passionately past boulders and over
waterfalls. Gradually the river grows wider, the banks recede, the waters flow
more quietly, and in the end, without any visible break, they become merged in
the sea, and painlessly lose their individual being.
人的生命应当像河流，开始是涓涓细流，受两岸的限制而十分狭窄，尔后奔腾咆哮，翻过危岩，飞越瀑布，河面渐渐开阔，河岸也随之向两边隐去，最后水流平缓，森森无际，汇入大海之中，个人就这样毫无痛苦地消失了。
Youth means a temperamental predominance of courage over timidity,of the
appetite for adventure over the love of ease.This often exists in a man of sixty
more than a boy of twenty.Nobody grows old merely by a number of years.We grow
old by deserting our ideals.
青春意味着战胜懦弱的那股大丈夫气概和摈弃安逸的那种冒险精神。往往一个60岁的老者比一个20岁的青年更多一点这种劲头。人老不仅仅是岁月流逝所致，更主要的是不思进取的结果。
Years may wrinkle the skin,but to give up enthusiasm wrinkles the soul.
Worry, fear, self-distrust bows the heart and turns the spirit back to dust.
光阴可以在颜面上留下印记，而热情之火的熄灭则在心灵上刻下皱纹。烦恼、恐惧、缺乏自信会扭曲人的灵魂，并将青春化为灰烬。
追问太长了，有没有简单一点的
