So here are the rules I’m going to try to follow:
One browser tab open. I want to focus on reading one thing, responding to one email at a time, doing one task in my browser at a time. I realize that I might have to open multiple tabs to work on something, and that’s fine, but if I have tabs open that don’t have anything to do with my current task, I’ll bookmark them for later, add to Instapaper, or add the task to my to-do list.
Know what I’m focusing on. When I open a tab, I have to consciously pause and think about what I’m trying to accomplish. That might be looking up some info, or writing something, or answering an email … whatever it is, I have to try to pause and make sure I’m being conscious about it.
