My mornings are for research. This has consequences:
• from 7pm one day till 1pm the next I have no internet access;
• my phone is in flight mode, so you won’t get me there either;
• I might answer the door, if you’re lucky, but probably not.
If you have a problem with that then consider this. Dealing with email will drain all the energy you throw at it, it will dump more email in others’ inboxes, in retribution they will dump yet more email in your inbox, and both your and their productivity and creative output will be shipwrecked.
If this makes any sense to you then read the following before sending another email to anyone: http://www.emailcharter.org/
