I'm young (24), so I guess I'm coming from a different mindset (entitled millennial here!), but the thought of working at a single place for life gives me nightmares.

Sure, companies 'evolve' (for better or worse) and theoretically your job changes as you climb the ladder, but surely you job learning and loving work if you do the same thing for 40+ years?

I guess this is the difference between people who see work as an obligation vs an opportunity.
