I hate it when questions like this come up in performance reviews and 1-on-1 meetings.
Boss - "Where do you see yourself in x years?"
Me - "Hopefully, retired"
I used to HATE this question every year when I worked for a large consulting firm.
But I used to "play the game" and come up with some corporate sounding bull crap using appropriate buzz words to make it sound like I looked forward to dedicating my life to the company until I dropped dead at my desk.
Then one year I just got sick of it and said "honestly, Bob, I'm planning on early retirement in far less than 5-years, so I have no "5-year plan" (well, I did, but it wasn't the kind of "plan" the corporate geeks would have considered acceptable).
He looked at me like I had an attitude problem (he wasn't wrong about that). He couldn't accept the answer, saying something like "see, that's part of the problem- you don't take the job seriously (he was right about that, too), you don't put in the hours (the guy was on a roll- I guess he noticed I was rolling in at 9:30 when the rest of the lemmings were there by 8?), you make a joke about everything (how else was I going to maintain my sanity?)."
Needless to say, the performance evaluation didn't go well. As I recall I got the John Blutarsky raise (zero point zero).
But I wasn't joking. I left within the year and early retired.
That's the bad thing about being financially independent, it can lead to not giving a damn about your career. :)
