If you're like most productive people, you're probably getting through several things on your to-do list, but not making progress on that one thing that you know is most important (and usually hardest).
Somehow that thing always gets left until later.
So it always seems like you're being "productive", but if you're distracted by a long list of priorities, are you being "effective"?
With "One & Done", the distraction of a long to-do list is gone. There's only one thing, and that's the thing you know you've got to get done. Your top priority.
如果你和大多数高效的人一样，你可能已经完成了待办事项清单上的几件事，但是在你知道的最重要的(通常也是最难的)一件事上却没有取得进展。
不知何故，那个东西总是留到以后。
所以看起来你总是“有效率”，但如果你被一长串的优先事项分心，你是不是“有效率”?
有了“一件事就做完了”，一长串待办事项的干扰就消失了。只有一件事，那就是你知道你必须要做的事。你的首要任务。
