Why become a manager?
I’ve told people considering entering into management that if they want well-defined problems, know precisely what they need to do, and want to put the job on pause when they go home at night, don’t go into management. If you want to have interesting problems that vary all the time and you want to feel like you’re making a difference - go into management. I don’t mean “management consultant” but an actual manager - of people, situations, products, and projects.
Don’t become a manager to boss people around. Do it because you can do the job better, take care of the team better, or make the right decisions considering everyone (the team, the clients, and the firm).
