早晨四点起来，开发个基于SpringBoot+微信小程序汽车服务系统。

困死我了。

送完孩子，然后去上班。

昨天有个读者朋友问小孟：程序员之间的差距为何如此之大。

有时候甚至在同一所大学，同一个专业，有的学生大四毕业可以拿到四五十w的年薪，有的学生毕业找不到工作。

甚至挂科、重修，延期一年毕业！[流泪]

现实就是这样，差距大的让人惊叹！究竟是什么原因造成了这样？？

我读本科的时候，大三时候我已经作为队长获得软件大赛一等奖，而有的同学才开始学习编程，研一下的时候，很多同学刚开始准备开题，而我已经接了很多的外包项目。

因为我一直在认清现状、反思、规划。

包括后来，有公司给我高薪、高职位，我依然认清现状。程序员这个行业很特殊。
