So. Who is happy here?

Genuine question although that may have sounded snarky. I know there's a lot of talk on burnout and shitty projects/managers. But who is genuinely happy (not corpo bullshit) with their jobs & why?

I was talking to someone who left MBB recently for personal changes but was very excited about & not burnt out by the work they did there. What are your "This is cool/happy" experiences?
