Lived in Australia for 2 plus years after meeting a girl while on a workkng holiday visa and spent 6 mths or so on a Kibbutz in Israel.
Loved my time in Sydney (Manly on the Northern Beaches), outside living, being near the beach, living healthily but as time dragged on the things I loved about home I missed more and more. When I got back vowed to adopt the things I loved about life over there and bring them to my life over here.Now Im pretty happy with my lot and made the right decision
One thing I do notice about some people who move abroad they cite stuff like congestion, crime etc as reasons for moving, but the reality is moving around this country your lifestyle can vary wildly.
If I had one piece of advice to people moving abroad, would be to chuck yourself into everything, push yourself out of your comfort zone or you risk becoming isolated and not fully enjoying the experience.
