[ Unreachable ]

Those of us who need time to do deep thinking, setting aside time to do undistracted work, probably have a love-hate relationship with that situation.

By that I mean, we know we need to isolate ourselves to concentrate on that work (such as really reading a document, doing a complex calculation, or drafting a reasonable email response to an unreasonable request). 

When doing that work, we should simply be unreachable.  We should have the phone off; email offline.  I know it’s hard to extract ourselves like that from being contactable.  But remember, teachers and pilots do it all the time.
