Got a new job as an App Dev Manager

So, got a new job. That's great. Pay bump, more / new responsibilities and all that jazz. It took until my first day on the job for it to like, REALLY sink in that it's my first job managing people. I want to be good at this, or at the very least, competent. I'm responsible for my team and I don't want to let them down. I'm already looking things up online, talking to my parents, friends in similar positions for more information, and figured it would be good to ask around on here.

I guess the other half of this is that I've gone from looking at code in the IDE to now being more responsible for higher level architectural decisions. Possibly company steering decisions. Not used to that yet either, or at least the feeling. I feel under-prepared, and am possibly verging on overwhelmed. Lots of new things happening at once here, also writing this to unpack it as I type it out.

What advice do you have for me? Anything that you've learned while in a managerial role that you haven't gotten to share? Tips and Tricks? Prayers? 🤣
