Having kids showed me how to convert a continuous quantity, time, into discrete quantities. You only get 52 weekends with your 2 year old. If Christmas-as-magic lasts from say ages 3 to 10, you only get to watch your child experience it 8 times. And while it's impossible to say what is a lot or a little of a continuous quantity like time, 8 is not a lot of something. If you had a handful of 8 peanuts, or a shelf of 8 books to choose from, the quantity would definitely seem limited, no matter what your lifespan was.

QuickAdd 的概念应该是借鉴于 Emacs 的 org-mode。 简而言之就是我们可以预设一些文件格式、动作，让我们通过命令就可以快速创建文件，或者按某种格式记录内容，比如我设定了这些预设动作，通过命令运行某个命令，我就可以快速的记录一个 Todo，或者输入一个标题则开始写文章，或者是记录一个单词，或者是记录一个代码片段
