I had several opportunities to leave this part of the world at around 18 and also 22. I stayed primarily because I felt like I had a lot to do there.
My 20s and 30s were spent living and working in nearly every South and southeast Asian country and it enriched my life tremendously.
It also gave me a better grounding to go and do other things elsewhere.
In general I feel a very deep sense of ‘I belong everywhere here’ that no degree of immigrant alienation can ever take away from me.
