Sometimes, people think they want to be "Managers." I tell them to stop worrying about that. Start ACTING and PERFORMING like a Director or VP, and then you can skip the Manager step.
I don't think people "always must care about their careers." I am pretty sure Bill Gates or Steve Jobs or Mark Zuckerberg could not care less about their careers when they started as employee # < 25. They just wanted to build a company and a business.
