Thinking about moving aboard. Am I crazy?

[Michecoco]

I have basically read everyone's opinion...and it's all great perspectives.
My first response to you would be to say: yes if you can afford it financially now, do it!
When you graduate, you can re-evaluate. Maybe a job takes you somewhere maybe you stay, but it seems like a good time to explore this lifestyle.
If the winters are too cold, you will adapt and find alternative solutions but you never know until you explore it.
Walk the walk! Live life! It will be something you can look back on and laugh and be proud of your efforts!
