I'm with Velociraptor on this, you can afford an 'I don't care' mode.
You can change your attitude and have fun with the office politics,
because 'you don't care'. If you do become "a little bit of an office asshole",
and you can keep track of the politics and do happen to get fired,
you might use them as a tool to get a package
for the firing or 6 months of unemployment.
Change the way you mentally process it and take joy out of it,
you're probably only there because of the people you are with,
whether coworker or patient, so enjoy them.
