The beginning of the end

Today is my farewell. I have looked forward to this day for 2/3 of my life (and the important two thirds, not the third I can't remember). It doesn't seem real. Honestly, I have never felt so nervous. Not because literally everyone in the world will be at my talk (yes, literally all 7 billion people), but because I want this day to live up to my expectations. It's going to be great. Scary as heck, but great.
