part1：how to practise your typing via writing a English blog
it's easy to write english for chinese. because currently we have chinglish actually.
In other words, with chinglish, you don't need to perfectly correct in English syntax. you can just type what you think, think what you want to write it done.
for a pre-programmer, normally he need to coding, and coding require typing. typing fast doesn't means coding faster, but at least you will not interrupt by seeking the location of the key you want. There is an advantage for english user in programming, because its directly to type, they don't need a extension layer for input/output, such like input method for chinese.
Also, typing in english and writing a such blog is good to practise your ability of expressing in English logic. this is both good for normal english thinking and programming thinking.
However, it doesn't mean I am suggest all people to do in this way. It just suitable for kind of these people:
1. low typing speed of phyiscal keyboard
2. poor english for expressing his mind
3. both above
If one day we programming do not require english anymore or massive typing with QWERTY keyboard, just forget about what I said above.
part2：为什么用左手我鼠标？
对于左撇子来说，这是很自然的，但也不是万用的。比如对于左撇子来说，大部分还是用右手玩rts游戏（可能会改键位）。
用左手或者交替左右手，利于缓解长时间右手手腕关节的劳损。同理，坐久了也应该起来走动，也可以站着办公（看情况
使用左手持鼠标，通常来说，的确会降低操作的效率，但相对的，无用的惯性操作会减少，效率的损耗其实不大。
至于有些关于左手能锻炼右脑的说法，我觉得都是可以忽略的。主要还是右手没必要一直长时间干着机械的操作
part3：总结
不要怕犯错，要不断试错，直到错误越来越少。错误无法避免，你不可能第一次就盲打成功，也不可能一个右撇子换左手用鼠标不会点错左右键。
let it crash是erlang容错的核心思想。原话是这四句：
- The world is concurrent
- Things in the wold don't share data
- Things communicate with messages
- Things fail
最后一句便是let it crash的体现。人有生老病死，程序进程也有对应的lifetime。不犯错是不现实的
