I believe you mean Imagine
It's not easy but I think this way:
My native language is German.
The most spoken language is English, though.
So now I imagine how it would be if my native language was English.
My decision: "Too bad that it's German, it would better if my native language was English".
My native language (my own one) becomes the most spoken language.
I can stay with German because everyone else has to learn it now.
But as said: Not very easy
