The second key is to weekly make an appointment with yourself for at least a couple hours a week, devoted to relaxation. It can be going to the gym, practicing a sport you love, getting a massage (on this subject, see this month's spotlight), sit down and read an entertaining book, do some knitting, whatever works for you. The key is that this is an activity that you enjoy, that you practice on your own (i.e. no co-workers to talk business while having a tennis game, no children interrupting you while you are reading your book, etc.) and that makes you feel refreshed once you're done.
