I've recently started working from home and found that because i'm not in an office environment, where the back stabbing and idea stealing vultures live, its much more relaxed and can actually get my head down and engross in what i need to do.
don't have to worry about office politics at all. Also when your all worked up, you don't have to pretend or invent work to do because your mindful you are being watched by an office full of chiefs!
plus the wife appreciates coming home to a clean, straightened house and a cup of tea, before the 3 kids come back and trash it all over again
