In Top Gun: Maverick (2022), the main character chooses to grow his career as a specialist rather than a manager.
He gathers awards, he’s a good specialist, but the benefits of a manager are more.
I think of several examples in real life in which, when going to be a manager, in order to be liked by others, you have to be a bit two-faced – politicians, for example.
Specialists may have some standards, but this might make them difficult to work with.
They might have some personal rules that are not suited for others.
For example, they could impose high standards on themselves and small standards on others. That’s fine when you don’t work in a team, but not when you lead/manage others.
