I quite like this article (despite some signs of AI writing in it). It reflects my own experience of transitioning to management roles.

The first time I managed a team I designed a whole solution for the team to implement, and they were like "Are we just your typists?!! Why don't you let us do that?". They were right; I stepped back and shared goals and direction with them instead from that point. It's hard to step away from how you did things before and give trust to others to do a good job.

The other thing they highlighted also resonated - if you become a manager of people who were formally your team mates, it alters your relationships with them. I remember feeling quite depressed when people no longer joked around with me in the same way they used to, and I felt a bit isolated. Took me a while to understand the shift in dynamics and not take it personally.
