While I was reading your story (great story btw), I kept wondering, "what would you have thought if you could share this article with your younger self just before you began your first odyssey?"
I like the descriptive sentences you used to describe the railway system in other countries. I read this above section a couple of times and notated it because it painted such an excellent picture! I would include more of those descriptive sections in your stories.
Of your five lessons, the last one about respect resonated with me the most. I couldn't agree more with it! Experiencing other cultures, traditions, and faiths allows you to respect others.
Overall, this was an exciting read, and I enjoyed it all the way through! Thank you for sharing!! I look forward to your next story.
