“当你老了，回顾一生，就会发觉：什么时候出国读书，什么时候决定做第一份职业、何时选定了对象而恋爱、什么时候结婚，其实都是命运的巨变。只是当时站在三岔路口，眼见风云千樯，你作出选择的那一日，在日记上，相当沉闷和平凡，当时还以为是生命中普通的一天。 ” 2022年春节前的最后一周工作日，工作节奏并没有轻松下来，然而我却忽然想写点什么。 记得在更早的年代，人们会写博客，我至今记得在MsnSpace上同学朋友里时不时就会出现一两篇让我至今记忆犹新的佳作。后来人们忙了，只会在微博上写下几十个字的短短一句话。而如今发朋友圈也只是身边少数朋友的习惯，有时候大家忙的顾不上说，有时候大家只是习惯了不在人前表露喜怒哀乐。 时间久了，难免有些感慨：生活中有些事，一旦变成了回忆，就难免模糊褪色。...

当我离开阿里的时候，离职信封里有张纸写着：退隐江湖。 每个人一生都离不开江湖。我感谢金庸老先生，给我们创造了那么精彩的武侠江湖。在青少年时代，读他的小说了解江湖：行侠仗义，宅心仁厚，舍生取义，快意恩仇…… 那感觉是何等的畅快，尤其每每读到小说的结尾，我总会有些感慨和期盼：希望自己能像书中的主人公一样闯荡江湖。 进入江湖这几十年，经历种种人和事，见识了伪君子、恃强凌弱、见利忘义等种种，才知道这是江湖的另一面。个中滋味，冷暖自知。这时候再读金庸的武侠，会感到温暖，因为他告诉我们：天地自有公道。书中的大侠，没有哪一个是一帆风顺。用现在的话讲，每一个主人公都经历过人生的至暗时刻。看到于此，也就释然。 年近不惑，看小说的时间少了，也很久没再重读金庸的小说。然而每每有人生感悟，蓦然发现其实金...
