Without really thinking about it I've developed a habit of not replying to emails on weekends (or at least not until Sunday night). It's not that I don't check email -- I do pretty much all the time via my phone -- or that I absolutely never respond to anything -- I will if it's of catastrophic importance or if I have five minutes I really need to kill -- just that I'm usually busy doing something with my family on the weekends and I find it much easier to let all of those messages pile up for a couple of days until I can deal with them all at once on Sunday night or Monday morning. There is rarely anything that requires an immediate response, especially on a Saturday or Sunday, so I don't feel any guilt about taking my time. So while this wasn't something I'd consciously decided to do, now that I'm aware of it I'm going to try and make it my new policy going forward.
