I am in my early 30s and after 10 years I still mostly love the job. I've dipped my toes towards management at one point and quickly felt overwhelmed and out of my depth, and realized I'm much happier when coding or discussing technical problems, explaining solutions and so on. It just feels like more useful, fulffiling work to me than updating reports, discussing timelines, people allocation etc.

Just giving my own perspective, not claiming anyone else's is wrong.
