Breaks, Exercise and "Off" Time
I do take occasional breaks to exercise and to surf the net. Giving myself permission for brief sorties outside my “production zone” insures that I don’t get burned out…which would really negatively affect my output! I might also add that I often take a day out of my work week to work around the house and I take several trips each year with at least one being a major one usually to some exotic destination. Giving myself plenty of "off" time keeps me at my best when I am working.
