“I used to suck at e-mail. I’d let e-mails pile up, get overwhelmed, and miss important messages—or forget to reply. So I set up filters on my e-mail, and that’s been working pretty well. Now, my inbox gets e-mails only from people in my company and from my girlfriend. A folder called Robots gets anything not written by a human, like bank statements and Google Alerts. Most everything else goes into the Unsorted folder. When I get to the office, I go through my inbox first and try to respond right away. Then I go through my Unsorted folder, but I respond to very few of those. I’ve found that if you’re not responsive to e-mail, it trains people to leave you alone.”
