Some years ago, writing in my diary used to be a usual activity.I would return from school and spend the expected half hour recording the day'sevents, feelings, and impressions in my little blue diary. I did not reallyneed to express my emotions by way of words, but I gained a certainsatisfaction from seeing my experiences forever recorded on paper. After all,isn't accumulating memories a way of preserving the past?

When I was thirteen years old, I went on a long journey on footin a great valley, well equipped with pens, a diary, and a camera. During thetrip, I was busy recording every incident, name and place I came across. I feltproud to be spending my time productively, dutifully preserving for futuregenerations a detailed description of my travels. On my last night there, Iwandered out of my tent, diary in hand. The sky was clear and lit by the glareof the moon, and the walls of the valley looked threatening behind their screenof shadows. I automatically took out my pen...

At that point, I understood that nothing I wrote could evermatch or replace the few seconds I allowed myself to experience the dramaticbeauty of the valley. All I remembered of the previous few days were the dullcharacterizations I had set down in my diary.

Now, I only write in my diary when I need to write down aspecial thought or feeling. I still love to record ideas and quotations thatstrike me in books, or observations that are particularly meaningful. I takepictures, but not very often only of objects I find really beautiful. I'm nolonger blindly satisfied with having something to remember when I grow old. Irealize that life will simply pass me by if I stay behind the camera, busypreserving the present so as to live it in the future.

I don't want to wake up one day and have nothing but a pile ofpictures and notes. Maybe I won't have as many exact representations of peopleand places; maybe I'll forget certain facts, but at least the experiences willalways remain inside me. I don't live to make memories--I just live, and thememories form themselves.

    程信，字彦实，其先休宁人，洪武中戍河间，因家焉。信举正统七年进士，授吏科给事中。也先犯京师信督军守西城都督孙镗击也先失利欲入城信不纳督军从城上发箭炮助之镗战益力也先遂却。景泰元年，请振畿辅饥民，复河间学官、生徒因用兵罢遣者，皆报可。明年二月，出为山东右参政，督饷辽东。巡抚寇深奏盗粮一石以上者死，又置新斛视旧加大，属信钩考。信立碎之，曰：“奈何纳人于死！”深由是不悦信。天顺元年，擢太仆卿。京卫马旧多耗，信定期征之。三营大将言太仆苛急，请改隶兵部。信言：“高皇帝令太仆马数，勿使人知。若隶兵部，马登耗，太仆不得闻。脱有警，马不给，谁任其咎?”帝是之，乃隶太仆如故。明年，改左佥都御史，巡抚辽东。都指挥夏霖恣不法，佥事胡鼎发其四十罪，信以闻，下霖锦衣狱。门达言信不当代奏，时寇深方掌都察院，以前邻劾信。征下诏狱，降南京太仆少卿。母忧归。成化元年，起兵部，寻转左侍郎。四川戎县山都掌蛮数叛，陷合江等九县。廷议发大军讨之。以襄城伯李瑾充总兵官，进信尚书，提督军务。至永宁，分道进。信与瑾居中节制。转战六日，破寨七百五十余。前后斩首四千五百有奇，俘获无算。录功，进兼大理寺卿，与白圭同莅兵部。信欲有为，而阻于圭，数称疾。改南京兵部，参赞机务。明年致仕，逾年卒。谥襄毅。

    信征南蛮时，制许便宜从事。迄班师，未尝擅赏戮一人。曰：“刑赏，人主大柄也，不得已而假之人。幸而事集，辄自专，非人臣所宜。”在南京，守备臣欲预钱谷讼狱事，信曰：“守备重臣，所以谨非常也。若此，乃有司职耳。”论者韪之。
