> doesn't define me as a human being
This is it.
I've had various issues with unrealistic requests and timelines from those to whom I report, and it feels as if I need to, somehow, "work harder" (whatever that means) to prove that I'm trying to execute their impossible plan.
When I get home, however, the mere presence of my wife and kids, and even pet(s), remind me of how I actually define myself, WHO I AM.
I like art. Be it paintings, music, film, TV shows. That's where I find "myself". I'm good at things I do for work, but I don't care about it the way I care about the meanings of life I can find staring into a painting, or listening to a song (anywhere from Mr. Bungle to Debussy) or watching a TV show (anywhere from Adventure Time to For All Mankind).
I'm privileged enough, and have planned ahead enough, that I could significantly downgrade my already not-very-prestigious, but quite demanding job, and live well.
My job doesn't come close to defining me, to myself anyway. That's probably the other "thing" - how people want to be able to define themselves to others. I'm relatively unaffected by that particular neuroticism.
