A piece of advice: Do not ever go to Vienna.
Unless you get bored with your new ENTP life, of course. I don't think you will. It is a happy life.
I went to Vienna as an ENTP and I came back as an INTP.
Vienna is gloomy and dirty. The clouds hang low there. The inhabitants are a bunch of uncouth morons.
I say the place is rotten. It can turn anybody to an introvert.
