The Onion’s take: https://www.theonion.com/unambitious-loser-with-happy-fulfil...
- Getting married
- Having kids
- Settling down to live in one place
- Finding out how you can participate in the local community, and the actively participate
You will find that people are remarkably open to people who willingly contribute to other's well-being. This is how friends are made, this is how roots are grown.

It failed both times. People are incredibly difficult to accept outsiders within their circle. I did get married, but wife wants no kids :( ... which makes the marriage a little... fragile. Without close family/friends holding me here (I am and feel like a complete stranger here, 10 years on, and my wife is not local either), it seems I could just go at any time.
However, blowing my life up a third time seems futile. It may work for some people, but after failing twice, doing it a third time seems stupid.
Unless you do it different this time.
There are places that welcome outsiders. And there are places where everyone is living as an outsider to different degree, even those who were born there, with only shallow bands formed out of habit. You can never feel at home in those places.
