I've been slowly working my way through the great book by Doris Kearns Goodwin called "A Team of Rivals." In this wonderfully researched and presented history, Kearns Goodwin details the life of Abraham Lincoln and those people whom he both competed against (the Rivals) and later asked to join his cabinet (the Team).
The book is written using letters and first hand accounts from people surrounding Lincoln and his election to the presidency. What strikes me most as I read is the pace at which the communication happens.
One of the nice things about living in the era before email and immediate communication was that people took time to think about what they were going to say and think about how they were going to say it. The patience that would then follow -- as letters galloped across the countryside and back again -- would drive us nuts today.
And it's rare to have that patience anymore.
I've read suggestions from others about managing our intake of data. One of those suggestions is to limit our email use to once or perhaps twice per day, setting aside certain times to answer the notes filling our inbox.
I can imagine changing a habit such as checking email would be quite difficult. However I can certainly see the potential upside to this. My life at work could slow down and become more effective. On the other hand, I realize that the people on the other end of the email chain may not be as patient as I might be. This could undoubtedly cause problems.
So what's the answer? I think the best solution is somewhere in the middle of an instantaneous response and waiting for the Pony Express to arrive. When going through emails, why not answer those mundane emails that don't require much thought first, and then cycle back to the more heavier involved-thought questions? And even then, perhaps you will need to give a response a good bit more time (or pick up the phone.)
An email response to a heavier request perhaps later that afternoon or the following day is OK. Life was pretty successful for thousands of years before computers and email. It will probably be okay if that response happens in six hours or 6 seconds.
And perhaps taking the time to think through a response in those six hours will save you that much in headache later.
