Take them all with you everywhere, just be clever about how you process and manifest them.  i believe that only if you can sense all, can you give all.  Repressed feelings mean self editing, putting up smoke screens, and distraction - none of these are good for business.  

well, your feelings kind of follow you where ever you go ;) if I understood you right, I can say, I keep my mind at work during work hours for one simple reason.. I only have one channel in my brain, if I start thinking about something else (love, food, places and events I'm going to that evening, etc) I won't be able focus at work, the same thing during eating (and other actions :)).. if I don't give it my 100% focus, I won't do it right or enjoy it
