Do what you love and are good at doing. A lot of people in management are definitely not cut out to be managers. (At least where I work) people tend to get promoted into roles of supervision and management because they're good problem solvers, but being a manager involves a completely different skill set. If you enjoy supporting people and teams, making it easier for them to do their work, getting them the information that they need, ensuring they have the professional development and work environment to thrive... then yeah, work on becoming a manager. If you like what you're doing and you're in high demand... then keep doing that. Don't fix what isn't broken.
