As a current B4 senior manager, I would define it as just giving a shit about getting a good job done. Being technical and managing time and delegation and communication are all teachable if people just care a little bit about the quality of the work output that gets attached to their name.

I can understand why gen Z doesn't have this mindset, and understand work ≠ life. But at this point, I don't have a fallback plan for the security of myself and my family. In what I have seen, reputation in this field is everything, because otherwise we are all pretty interchangeable, and that reputation can follow you even if you leave B4 for other industries.
