Do yourself a favor and forget about the standard message.
The message they tend to use looks like this: Opening a word document, writing down a line that she has already heard a million times before and hoping that you are one of the twenty guys who wrote the same crap who she will actually reply to is not the best way to start a conversation online.
It is definitely nice to know that you like the fact that she is well-travelled but does she have any proof that you not just say that without meaning it?
If you only tell her that you like the fact that she is well-travelled without linking this characteristic to yourself, she can easily get the impression that you just say it to impress her.
In the online world things are a little bit different.
Men are a lot less afraid of writing to women than they are of talking to them in real life.
A couple of years ago you were frowned at when you said that you met your girlfriend on an online dating site. Today people are rather shocked when you tell them that you met your girlfriend without the help of modern technology.
