Today I gave a presentation at a UW systems research seminar, due to invitation from Hank Levy (the current chair of the UW CSE department!).
I had been nervous a few weeks before, but when I started talking today I was very smooth - in fact, I was surprised at how easy it was. Of course, there were some slides which were less relevant, I could have had a more smooth delivery at times, and my body language was a bit off (I fiddled with my hands quite a bit, said umm, etc.) Overall, however, I'm pleased.
