Prior to being acquired: 3-4; VC's, customers, employees, all managable
First 9 months after being acquired: 9-10; seriously sick several times after several "pissing" matches with new boss
Lately: a shakey 7-8, we're both trying to make some compromises
Just back from 2 straight weeks of working fun: central PA-Phili-Frankfurt-Dresden-Frankfurt-Milan-Frankfurt-Tel Aviv-Frankfurt-chicago-Tampa-Phili-home. (Dinners at 11PM, luggage stuck, missed meetings, worthless meetings, entertained by a few security line and passenger-flight attendent mishaps, etc). My favorite was Chicago-Tampa on United (Ted). Full flight, I had the isle and another guy had the window. Between us was the largest woman on the plane. He was mashed against the window (couldn't really see him) and I was leaning into isle, which is always good for a few accidental cart bashes.
I look on the bright side; no food posioning, decent weather, kept up with my workouts, only one night in Frankfurt with no luggage (sink-hair dryer clothes washing routine), and home in one piece for a few weeks.
