As to introspection, perhaps some more is called for. You refer to your colleagues as "subordinates" and think of yourself as "boss, leader..."

That's not the proper mindset to be successful as a manager in high tech. You're there to clear hurdles for individual contributors who are more technical than you (if they're not, you are either a junior manager managing even more junior engineers, or your company does not have a technical track to attract/retain good engineers), so that they can do their jobs more efficiently.
