# 我为什么会选择 cs 课程？
我是从小学大概三四年级（18 年？）开始接触电脑吧，就产生了浓厚的兴趣。那时候智能手机其实早已兴起，全世界掀起了智能手机热潮，Apple 推出了 iphone7 (现在还留着一台用 infuse 看番) iphone8，微信支付已经遍及千家万户。然后，理所当然，电脑这个又笨重又贵的东西渐渐得被时代潮流淘汰了，那些年人们讨论的更多的是新一代 iphone 和某国产品牌哪家强，而不是 intel 又推出新一代 u、NVIDIA 推出 20 代显卡了
喜爱计算机大部分是遗传吧。我爹从小没见过手机电脑，一遇上就一发不可收拾，当然也深深感染了我。。他经常买配件装机，让后搞 nas、翻墙、下 bt，带我看电影 —— 生化危机、终结者、异星觉醒 都 tm 是重口。。我当时才三年级啊啊啊啊然后，我就渐渐开始接触电脑游戏，pvz，Minecraft，GTA，以及，4399 唯一真神的死神 vs 火影，战火英雄，生死狙击。毕竟玩游戏需要技术支持，对硬件软件操作系统需要一定了解，就慢慢开始接触了 cs
当然，这么多年的摸爬滚打下来不过还只是学了一点皮毛。什么翻墙装机双系统拆硬盘不过是鸡毛蒜皮，我还真没有浅下心来深入学一门语言，现在顶多算个小白。。
编不下去了，反正最后选择了 cs 课程，希望能开开心心的学习。当然，我会在博客上记录我学习过程的点滴
那么开始吧。
