I really like Dora's reaction.
And Claire... it's good to appreciate what you have, but it's unrealistic to always do that at 100%, all the time. Comparing yourself to others is madness, and it doesn't actually help people who are in a tougher or less appealing situation. Guilt-tripping yourself in a "I have a headache, but there are people out there living with chronic pain" way is not healthy for anyone. You're still having a headache, it still sucks, and it's OK to feel crappy about it.
It's OK to hate your job. In fact, I'd say it's way underrated as a feeling. It's a JOB. It's not guaranteed to be satisfying or fulfilling, it's a way to make money first and foremost. People who genuinely love what they do are few and far between, and it's a form of privilege.
