Calm?

I'm on an airplane from Greenville to Detroit. You would think I would be full of excitement or shaking with nerves. Surpizingly, I'm neither. I feel a sense of calm that I most certainly didn't expect. Is it because I really am ready and prepared for whatever awaits me across the world? I wish!! More likely, I'm in some sort of denial over what I've gotten myself into. 

Pictured; perhaps the last drink I will have for a while that contains ice, and I'm too cold to really appreciate it
