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.
