> Practice enough to transform your though process from "I'm nervous" to "I've trained for this." I probably over prepared, but I'm the kind of person who would rather show up too early for an airplane flight than to endure the stress of maybe missing the flight.

Congratulations on joining Microsoft several years ago! I like how you frame the benefits of practicing. I am totally with you on the showing up early for a flight. Pre-all those screenings, I once drove a family friend to the airport at 80-85+ mph speeds (never ever again!) so that they would barely catch their flight.
