好友大志因為是"Things"的愛用者，很希望"Things"可以支援把建立的工作輸出到行事曆上，直接建立行程。
於是Mail了一封信給"Things"的開發團隊，建議下一版能增加這個功能。
開發團隊也真的回給了大志Mail，倒不是說會在下一版增加這樣的功能，而是說明了"Things"這套App當初設計的哲學。
我請大志轉寄了這封信給我，細細讀了以後的確如大志所説，對GTD這套系統似乎又有了一些新的理解。
以下是大志寫給Things團隊的信，跟他們的回信，已徵得大志同意轉載。
Hi there,
I really love things,and I bought the iPhone Version.
I now try the Mac version and try to co-work with my iPhone, Here's the problem I have now:
I hope when I add a item in my Today/Next Action/Scheduled , it will appear in my iCal automatically.
So that when I launch my iCal on my iPhone or Mac I can trace a week plan or month plan.
I tried to find some cues in preferences and it  didn't work like what I want.
please help me. thank you .
Things團隊的回信
Hi ,
Sorry for the late reply, we are very busy at the moment. Great to hear how much you love Things.
In short, Things does not allow you to export tasks to a Calendar. To help you better understand why, let me explain the philosophy behind Things and how it is meant to be used.
Things allows you to capture, process, structure, and review the things you need to get done, in addition to creating a tactical list of items to accomplish during a day via the Today list. You might recognize these steps: Things’ design is informed by Getting Things Done, though it’s by no means endorsed by David Allen and we understand that people will use and want to use it in different ways. Essentially, the design and development team believes that, much like Allen lays out in his system, a system for managing your tasks is separate from a place where you keep explicit times and reminders. That’s better suited for a calendar.
The way I best understand Cultured Code’s design decision is this: we often mix up the times we’d like to finish something with a time when the thing is actually due, or, to be more direct, when the thing will become impossible or die altogether. This is important to remember with due dates, but could become even more fiddly and even more of a time suck with explicit times.
Keeping these tasks in a calendar allows you to manage your time-sensitive obligations with yourself and others. An example of something that needs a due date, to me, would be something like a meeting: you’ve scheduled a time with someone else, and that obligation you’ve created will be difficult, if not impossible to revisit if you miss it. You could reschedule it, but simply not showing up will cause problems, and you probably won’t be able to have the meeting if you simply show up two hours later. Thus, the due time in this scenario is much firmer and, I believe, better suited to a calendar.
Calendars (like Calendar/iCal and other apps) offer this kind of view of your obligations, in addition to bonuses like per-to-do alarms. Things doesn’t try to replicate the functionality found in a calendar. We think it’d add friction and more (though not more useful) metadata to project and task management, while ultimately not helping very much as there are already tools that do this much better.
Hope this helps you to understand the thought process this a bit more. Let me know if you have further questions, as I’d love to continue the discussion. We’re open to feedback, so thanks for letting us know how you feel.
先回到大志希望Things增加的新功能，可以將紀錄在Things中的事項直接加入行事曆中似乎是個不錯的主意。
可以不需要多做一個把Item轉發到行事曆的動作，對使用者來説似乎是很貼心的改進。
但回到GTD的本質，應該是一個用來紀錄腦海中所有大小事項，然後依照下一步行動分類，大量批次處理事項的系統。
GTD可以幫你紀錄下所有需要在電腦上完成的工作，但卻不該用來取代你的電腦。
如果你有一個行程需要加入你的行事曆（或是確認你的行程有沒有空？），你可以運用GTD紀錄，然後當你坐在電腦前，一次解決所有跟行事曆有關的事項。
或者，當下立刻確認你的行事曆，並把行程加進行事曆裡。
並把這件事情拋到腦後，因為你的行事曆已經幫你作了紀錄，接下來你需要作的只是定期檢視。
於是我把我的小小體認再回給了大志。
所謂的GTD系統，就是要幫助我們清空我們的腦袋，跟透過批次處理大量解決互相類似的工作，並節省我們寶貴的時間。
而透過GTD系統所節省的大量時間，並不是為了作更多的工作。
而是為了讓我們可以在更有效率的情形下，進入「流」的狀態。
把重要的事情用更好的品質處理好，會得到更好的效果；還能空出更多的時間，再提升。
