Yeah...here is some advice...RELAX. Stop with the rules, you will finally be free to do WHATEVER you feel like. Do you remember the first day of summer after you got out of school? The freedom? The ability to do whatever? Well...you will soon be there, but this time it will be SO MUCH BETTER. I can't offer specifics as to what you should do when you are finally free, but here a few suggestions...
-Get up when you feel like it
-Drink whenever the hell you want
-Lunch? Sure, if you feel up to it...don't COMMIT yourself, though
-House Repairs? Only if the roof is leaking
You will have plenty of time to find your "groove" without having to plan anything out.
As far as the countdown goes, I had a whiteboard that I had the remaining number of w*rk days written on it. Everyday before I would leave, I would update it. When it was all said and done, I was very surprised at how fast the last couple of months went.
