I never traveled until later in life, so it was always a scary experience for me. Now that I have been around the world several times, I am more comfortable.
I’ve been through some of the worst airports in the world and survived.
One time I missed a connection in San Fransisco. I thought it would be the end of the world, but I got to stay overnight in a nice hotel and had a pleasant and relaxing breakfast before my flight.
It’s all in how you react.
