I am sorry but this seems somewhat contradictory:
(i)They are arrogant and ignorant to any feedback they don’t want to hear.
(ii) They seek too much advice from too many sources with too many conflicting views.
Seeking advice is the opposite of being arrogant, and if seeking advice is a mistake it's only because you listen to too much of it, thus making you too responsive to other people's thoughts, not ignorant towards them.
