I have many emotions as I prepare to leave for Singapore. I feel the best representation of how I feel is quoted in the movie Armageddon as Owen Wilson's character is being strapped into the rocket just before going to save the world:
"I got that "excited/scared" feeling. Like 98% excited, 2% scared. Or maybe it's more - It could be two - it could be 98% scared, 2% excited but that's what makes it so intense!"
