I have taken on a role of a programming manager of my team over the last two years. I still have some programming responsibilities, but I do about 95% management work now.

Pg had that essay about maker time and manager time that is spot on. Transitioning to a manager role is a different skill set.

I would highly recommend the following two books

The Coaching Habit by Stanier

and

Extreme Ownership by Willink and Babin ( audio version is amazing )
