For the next 5-10 years (the last before retirement), I planned to keep worrying about whether Amy in Accounting was going to stab me in the back. In fact, I applied for a "sure thing" promotion and have spent much time worrying about whether I will get it or if it will be derailed by forces outside of my control, which would mean I'd have to be outta here and it's not easy to get another job at 60. I even had a nightmare last night about pissing off my boss (who I've pissed off maybe twice in 9 years) and losing the promotion. You're right. My job lives rent-free in my head at all hours of the day and night and that's just wrong.
