"That's what gets done, of course. The urgent," writes Seth Godin. I've an attitude about e-mail urgency.
In fact, I'm suspicious of emails containing exclamation points. I tend to sneer at them. I used to set my Outlook toast to sound a claxon whenever an URGENT email arrived in my in-box. That annoyed a lot of people whle also making the point that overusing the imperative makes you no better than the boy who cried "Wolf!" too often in the pasture.
I've also a well-honed habit of pigeon-holing my e-mail into small windows of opportunity during the day and not watching the mail counter tick upwards while I'm doing real work. That personal work practise evolved in the heels of getting too many urgent requests for attention.
