Successfully defended my PhD thesis last night. Knocked it out of the park. I spent the weekend getting my slides ready and they weren't just super well put-together, but I even coordinated 'em with my (super cute, femdrogynous) outfit. I answered my committee's questions with speed, aplomb and wit.
I didn't even practice my talk, so my confidence in the subject material really shined through. The only awkward bit for me was when I ended my talk by walking over to my little bottle of juice (also coordinated to my outfit), downed the last couple of inches, swallowed, paused for a moment's thought and said "aaaand, that's my talk" with a bit of a lazy drawl. I should have thanked my committee. Instead of being appropriately humble, I was flippant and cocky. Oops! So that's why people practice for these things!
