It's getting more interesting when you have mastered a language to such a degree, that you can think in it. Having lived the first half of my life in Russia and the second in Germany I can think in both, russian and german, and switch between them instantly. I found out, that I am more happy and more relaxed while thinking in Russian, while thinking in German helps my problem solving skills. Probably it's correlated with my life experiences. I also talk in a higher, more boyish pitch while talking in Russian, while my German voice is deeper. At parties I often enjoy talking in English, as I have no cultural baggage at all associated with it, and can use it to say things I would hardly say in any other language (knowing how it may be interpreted). While it has its upsides (being able to switch to another cultural mindset on the fly helps with taking things easy), having two personalities occupying my brain makes both of them less deep, and while it's more or less interconnected now, translating the pieces of information between the languages feels often impossible in polynomial time.
