Prussian army based on Officers’ Code of Honour.
Von Rundstedt excellent learner, respectful and cheerful.

Von Rundstedt always respected the separation between the Army (whether the Reichswehr, the Wehrmacht) as an executant and the Government as a decision maker.
Von Rundstedt always left maximum decision latitude to his subordinates.
Hitler was actually quite good at gathering different opinions, changing his mind when needed, and keeping the right people around himself.
The Night of the Long Knives: be very careful of cunning power-loving people.
XXX indebted himself personally with Hitler: not good.
Guderian was brilliant (mastermind of the A XXX plan)

Von Rundstedt could have been more open to knew technologies (e.g. Guderian’s Panzers): his personal attraction to the deprecated cavalry probably participated in him blinding himself.
Hitler was directly intervening and overriding way too much in the operations. He should have stayed more into a goal-defining position.

It is more important to share the underlying reason and thinking-process behind knowledge and decisions, than the knowledge and decisions themselves.
