I am an immigrant and know LOTS of people who have moved to a new country they now call home.

You mentioned, "Universities abroad offer curricula that align perfectly with my evolving interests. But it's not just about professional ambition. Climate anxiety pushes me toward regions with sustainable infrastructure", but based on my years of observations, I have concluded that Universities in western countries are simply indoctrination camps where they brainwash people and in many eastern countries, you are expected to simply memorise things rather than THINK. As for 'climate anxiety', do not even worry about it because worry alone solves nothing. The climate HAS changed constantly and WILL CONTINUE to change constantly, REGARDLESS of what humans do. Humans cannot control NATURE- it is like expecting an ant on Earth to change something on the Moon. 'Climate change' is a meaningless phrase used to invoke fear; nothing more. Please do not use and perpetuate nonsense phrases that are used as a weapon on mankind.

"while preserving your own cultural roots."
WHY? Why do people cling to cultural ideologies? Not all cultural ideas are good. Some need to be abandoned. I use common sense and logic to decide which customs are positive for humanity and which are not. I keep those that make sense and drop all that do no good.
