I'll finish my travel day real quick-like:
Arrive to second airport, procede to run about 2 miles to another terminal (underground, up, down escalators, etc), to find that I missed my original flight. So I had a couple of hours to spare...
Made it back to the home-area airport, with two hours of driving time left. And that's really where I got into the deep thinking. Things like:
what were my goals for myself when I was in high school/college?
Are they coming true?
way back to elementary/middle school -- what were my dreams?
Are any of my dreams coming true?
What have I accomplished?
What are my goals for the next few years?
Should I set goals for my personal or professional life? (or both?)
Made it home in one piece, but it was rough emotionally.
