I remember my first passport, I was 17. It was a thrill. A sense of freedom to fly outside the USA.

My passport had been expired for a long time. I renewed it when I got my job in aviation. It was still that sense of excitement when it arrived in the mail. I encourage people all the time to get their passport, it gives one the freedom to go somewhere anytime (of course, if a visa is required that may not be possible!). If an opportunity comes up and you are invited to a different country, voila you are ready and able to go!
