Pax!I've been listening to some documentaries on the famous keyboardists and it seems like most of them were lonely and introvert people. What do you think? Are keyboardists generally introvert people (not that his must be something bad)?
I'm recalling research but the significant majority of soloist performers are introverts.
and although they are introverted they want to become famous people
No, the vast majority of them don't. Most are happy just to do it because they love it.
Few people achieve great things because they set out to do "great things." They achieve great things incidentally because of their love, passion, and interest in them.
A presenter in one of the music conferences I attended did an unscientific study of how many people in attendance thought they were introverts. 75% of the room considered themselves introverts, the other 25% extroverts. The population was mostly made up of pianists, organists and choir directors.
If our instrument is not a piano then our social circle is limited to the group in which we rehearse or perform. These reasons alone will limit our possibilities for social interaction. It's that simple.
Intraversion is one reason why intraverts take up solitary activities. Intraverts tend to avoid large groups. Playing an instrument has the added benefit of taking up time and avoids undesirable social situations. But, we don't take up piano to avoid people. We'd avoid people simply because we don't feel comfortable in such groups.
...Now one quick word to all you young single adults. Make sure your future mate is involved or has been involved in some sort of show business (where the "show must go on"). Otherwise they won't understand your dedication.
