It's a good way to think about it but it's subjective. It's always my first name that causes the problems, rather than my surname, and I don't really have a problem with people pronouncing it slightly differently and it's usually a decent approximation. A friend of mine is called Jean-R?my, but he'll introduce himself in England as John. Each to their own, I suppose.
I have the same problem here.
I don't mind the close approximation - there's only so much you can do about an accent and the way your articulators shape sounds, depending on what your native tongue/accent is. You can train it of course, although I have to say that you are probably more keen to do this if you work in a related profession (it's still very common in singing and acting - both to eliminate native accents and to learn new ones).
However, some people don't even try and force their own pronunciation on you instead (I even had people trying to tell me how to pronounce my own name - now that takes the biscuit I guess).
I have to admit though that if I want to avoid a spelling marathon or repeating myself, I pronounce my name the English way, especially over the phone.
pushpull, did you ever hear the older Germans calling it "Volleyvott" (closest approximation without using the phonetic alphabet)? My gran used to say it that way, and I never quite understood - even if you read it out using German phonetics, it can only be "Vohlvort" at the most. Where does the "Volley" come from?
I admit I am a bit of a sucker for languages, annoying enough I will never do all of them justice. I always say: If in doubt about a name or proper noun, do as the Romans (Swedish, ...) do and try to get as close as possible:
