Take a leave of absence and maybe your answer will come.
Thanks everyone. These are good thoughts, and very much appreciated. I have considered a leave of absence, but in my job, there really isn't such a thing. Running sales (for the Americas) for a large group within my company doesn't give me much flexibility there -- in fact, last time I took two weeks vacation in a row... hmmm. Early 2000's sometime perhaps.
I have thought about trying to reduce the stress in my job, and I've taken several actions to do that (I no longer go to work at 4:30AM, I go to the gym more regularly, I *try* to not work much on the weekend, I do my best to take a few days of vacation here or there), but it's still high stress more often than not. However, any job in sales will carry with it at least some inherent stress, I believe.
The thing is, there are some days I absolutely dread going to work. I mean, Monday's are usually terrible. Next Sunday-Thursday when I will be traveling will be terrible, and the work will just stack up.
Our office manager is retiring next Wednesday. Moving to be closer to grandkids. She told me that next Wednesday will be a very, very difficult day for her, and that leaving will be traumatizing. What I didn't say (but thought) is that the day I leave I will be walking (running?) out laughing like an insane person. To leave the shackles of day-to-day issues, problems, customers, escalations, meetings... this will be a joyous day.
Plus the whole "will I be bored in retirement?" thing has me thinking, although I'm sure I can come up with a whole ton of things to do.
I think at the moment, I am 75% running from, and 25% running to.
