可以想成：你在一件事上簽下名字的那一刻——從現在起，你未來的一部分已經被綁住了。這個字接下來可以指畫面裡的任何一塊：你給出去的那句話、你持續投進去的心力、行事曆上因此被佔走的那格時間，或是每個月固定被扣走的那筆錢。共同點都是「已經答應出去、收不回來」。From the picture
因此被佔住的時間與金錢
把鏡頭移到承諾的另一端：答應了之後，你的行事曆、你的錢、你的人力就有一塊被鎖住了，這些被鎖住的東西本身也叫 commitment。

Something you have promised to do or that you must do, which takes up your time.
