It’s you who will have to say no to the higher ups when they demand that you drop everything and start working on quantum computers because their brother heard about it on a birthday.
It’s you who will have to argue with other managers and team leads when they want to push work on your team.
It’s you who will have to step up when team members get into bad arguments with each other.
You will have to accept that your job will leave less and less time for the technical side you’ve done before.
You are no longer the same rank as your team members, never forget that. Because they won’t, and if you get into technical arguments with them they might follow your idea because you’re the boss, not because you are right.
If you can’t or won’t want deal with these kinds of things, please don’t take the job. Management is a real skill.
