One of the challenges can be not being used to the new environment.
Another can be facing different distractions that you are not used to.
You can also have the problem that sometimes when you want to do something like for example if you have trouble with homework, but you can't do anything about because you don't have the same resources like you did when you were at home.
Sometimes also, when you are in a different country, they might have a different culture or way of living like you do.
Another problem can be the language if you are in a different country because sometimes, they might not understand what you are trying to tell them.
I hope this helped :)
Answer:
The line in the excerpt from Eugene O'Neill's "Beyond the Horizon" that reflects the idea of pursuing one's dreams is:
And I’d promise myself that when I grew up and was strong, I’d follow that road, and it and I would find the sea together. (With a smile) You see, my making this trip is only keeping that promise of long ago.
Explanation:
The first part of the excerpt explains how the character gets introduced to a world of dreams and as the conversation moves on, he comes to the lines that express his idea of pursuing his own dreams of going away and see new places, as he mentions the sea, that has been his objective since he was a child and he promises to see it one day.
