Dealing with difficult people is a pain in the ass. I am sure that everyone has to deal something like this in some point in life.
How does on deal with an incompetent person? Let them sink and take the project with them? Cover for them? Replace them (ideally?)
Or what about people that are just plain assholes? Push back? Tolerate and minimize contact? Be indifferent?
One thing I've noticed so far is that the people that get paid the big bucks are the aggressive but likeable people. How does one become like that? I have much observing to do and the finance industry is the right place to do that.
