The curse of the leader is that you cannot lead a group of people out of somewhere if they don't really want to leave. If you try, you end up becoming one of them.

I agree that corporate culture is dynamic and that you can make a difference, but you need to find if there is a group of people that is willing to change. Then you need to understand and put in concrete terms the vision that the group already have but does not quite understands. If there is not vision, the only option is to move on.
