Such a cycle
出自老舍的《养花》一文。“如此循环”的意思是：疲劳时就侍弄一会花草，放松一下，然后再投入写作，如此交替重复。“把脑力劳动与体力劳动结合到一起，有益身心，胜于吃药。”
我们改造工具，工具也改变了我们，如此循环往复。
We change the tools, and the tools change us, and that cycle repeats.
如果你还是专注于一样来改变，那么你同样还会成功，下一次的改变则建立在第二次成功之上，如此循环。
If you focus on just one habit you'll succeed at that too and you can then build on that and so on.
停下来、重构、稍微落后于特性、专注于少量特性、不赶进度而是优化代码，如此循环往复，却从来不受益;这样的状况完全有可能。
It is entirely possible to stop, refactor, be a little behind on features, slam in a few features, not catch up but screw up the code, and loop forever, never getting benefit.
