Not convinced? Numerous studies of people who attend meeting AND do emails at the same time do both activities poorly. Their contribution to the meeting is mediocre and their email responses are ambiguous and/or inaccurate and/or off-target and/or lacking in useful content. Go back and re-read some of your emails that you sent while you were in a meeting – are they really as good as they should have been, or just sufficient.

I don’t mean read a chapter in one and then a chapter in the other, or a page in one and a page in the other, or even a paragraph or a sentence in one and then the other. Read both books simultaneously, word for word. Let me know how that works for you. I already know my limitations.
