That’s especially true if, as in many of these stories, there was little to no planning involved. I understand that a lot of these “walk-aways” happened under duress and that in those situations there’s no time to plan. But for those who aren’t desperate and just want a change, going to a brand new place without a plan is going to lead to misery more often than not.
The common thread that leads to success, from what I see in these stories, is deliberately seeking out a community and/or family of choice to connect with in the new place. Without doing that, the prospect of the happier life sought becomes a real toss-up.
