Change of Scenery?

I have had the most productive day of all ... the first one in many weeks..AND I AM ON VACATION! My host had a prior work engagement today and I have spent the day sitting and working diligently. Is it the fact that I am not in my own home or my own office? Is it the clearer mind after several days away from it all during the holidays? Is it the sense of impending doom if I don't get my butt in gear?? Whatever it is ...thank you! I needed a day of moving forward.
