TAKE "FREE DAYS"
It can be "free days", as Dan Sullivan calls them, which are midnight to midnight, with absolutely no work or anything that is like work (no files to read on the beach;
no intense self-improvement, though light reading is ok). Just do whatever you feel like, a little like suggested in the wandering around with whim, as in the book The Artist's Way.
Do at least one every other week and it is recommended that you do one every week. Yes, you do have time. And these types of days make you so much more productive during the other days.
THE COMPLETE REJUVENATION NO ACTIVITY DAY PLUS
Set these up ahead of time on your calendar. Once a month is good.
This is the day where you eat an early dinner the night before, go for a walk, set up everything (all snacks, reading material, etc. so you do not have to prepare anything the next day, no TV though), go to bed early, wake up anytime and read or nap but no to do’s, no phone conversations, no internet browsing, no projects, etc., sleep as much as you want – the objective is to be totally refreshed by the next day (so you need to go to sleep early that night, too, despite all the naps!).
(This complete rejuvenation day is a must when one is exhausted and/or stressed out!)
WHO SHOULD DO THIS?
Everybody who needs to get away. A retired person who gets caught up in the day to day and gets stale. A housewife. Anybody.
