Email takes up more of my time in the day than it should. I just spent my first hour and a half replying to critical emails - not all my emails, just the most critical.
Of course, it really doesn't help that I have three accounts I need to keep track of: a personal, a work, and a professional. There's actually a fourth, but that's just a junk account for when I need an email to sign up for something - it just needs emptying once a week or so.
Maybe I could acquire a minion of my own, just to reply to emails.
