What you have written are well known truths, but everyone needs friendly reminder from time to time. Anyway, what does "perfect emigrant" looks like? I believe there are some people who feel at home in every place they find themselves in. It's not about preparation, it's not something you can acquire, it's a state of mind (or soul). But then, nobody is really perfect, so patience, energy and open mind would be sufficient to survive and thrive in a new place. Cheers!
