Related to the last concept, pick a set time to read email, you need to have a frame of mind that says I'm going to look at it. I'm going to think about it. I'm going to respond to it. It can't just be Oh, letting it come in, or Oh, I'm about to go to bed love o'clock at night. Let me look at it. And then there's someone upset and angry with you.
Now you can't sleep all night and you haven't responded to the email that is destructive to your productivity of many, many levels. My advice is, have a mindset that this is going to be your email time. You can decide I've got to do it all in 10 minutes. I've got to do it and 20 minutes or an hour a day. It will expand the amount of time you get it. If you tell yourself you're going to handle your email in 10 minutes, typically, you will so have a set time when you're going to check your email with the idea that This is going to be email time.
And I'm going to read it carefully. I'm going to deal with it carefully. And I'm going to get my email box to empty or near empty
