I have rules for myself about email. One of which is not to check email in the first or last few hours of the day.
I prefer not to check in the morning because I want to focus my energy on initiating and creating. Creating is hard work, and I’m usually tempted to go to email as a way out of the difficulty. It’s much easier for me to respond to incoming emails than it is to create and initiate things that matter.
Responding is what emergency personnel do to a 911 call. Responding is what you do when a glass gets knocked over at the dinner table. Responding is what you do when you realize that your parking meter time has expired and you see someone writing a parking ticket.
