I think thats a good start probably haha. I am not a manager, and have not had a "good" one in a very long time, so I have no resources unfortunately. That isn't to say mine are bad, they let me be autonomous as an IC and I have a lot of flexibility. I am coming more from a human angle, and not a "these are the 5 things you need to do to be a good manager" angle. In my company, most people are too busy with day to day activities to really focus on developing people. When I parted with my last one, he thought we had only been together for 2 years...it had been 5. I think a lot of managers just don't really listen, they nod their head and give some advice and then 4 weeks later we're just having the same conversation again.

Everyone's situation is different, so without context this probably just reads as pouting or possibly me being incompetent haha.

radical candor is a good book that explores a simple framework for people management.
