And that allows you to do something really, really important with the weekly review, and that is to make course corrections and small changes to your habits and to the way that you work.

这样你就可以通过每周回顾做一些非常重要的事情，那就是对你的习惯和工作方式进行完善和微小的改变。

This is an amount equivalent to the sort of course correction which might need to be applied to something that was in danger of colliding with Earth.

这相当于可能需要应用于有与地球相撞危险的物体的那种航向修正。
