Remember Merlin Mann, the evil mastermind who in the early 2000s conceived of a new method of psychological torture called “Inbox Zero“. Alas, this ascetic concept can mean different things to different people. Does it mean an inbox totally devoid of any emails (i.e. a literal definition), or does it just refer to zero unread emails (see here, for example, for a defense of this more flexible interpretation of the Inbox Zero concept)? However you interpret the meaning of Inbox Zero, what if we could just eliminate email altogether?

Never ending work e-mails = my own personal bell.
