I used to watch an episode of The Office (American) every day before I went to work. Just to remind me that it could be worse.
In no particular order, mostly current:
The Office (American and British)
Sports Night (I Survived Draft Day at Sports Night)
Parks & Recreation
The West Wing
The Good Wife
All Law and Order franchises (except terrible Criminal Intent)
What else? God I love TV. Also, if you ever need to learn about mentors, and how to be and have one, watch Sports Night, which has some of the best mentorship and work-friendship relationships ever on TV, for my money. The Dana-Natalie relationship, the Isaac-everybody relationship, the partnership between Dan and Casey, it’s all so deeply wonderful, genuine, and lovely.
