I have confidence in my knowledge of my craft, but those guys and guyettes make me feel as if I'm a decent teacher, and that the fact I genuinely care about their progress is actually valuable. They are... a cause. And I really lack the words to describe how meaningful that is.
On a completely different note, my gods, Agents of S.H.I.E.L.D season 7 is hilarious. I had to re-watch season 6 because I forgot all of it, and it was very good and essentially a romance story and trademark excellent Whedon multi-layered everything, and then there's 7, being absolutely piss-your-pants-off, while still being heartbreaking, fast-beat, witty, scary, campy, clever and thought-provoking. Nope, still not Firefly or Dollhouse, but really very, very good.
...Wait, how'd it become seven in the morning?
