How Active are Musicians From Late Generation X?

I was looking through a list of blogs by violinists, the most active seemed to be the one named "Plucky Violin Teacher."  It seems she must be very active in her passion.

I went on to review the next blog, and she teaches plus performs.

You know, I started off violin in a group class my first year of college for Music Education.  I decided to try to learn it when I was 29 about to turn 30 in about a month.  I feel I could have had a good career.  I'm 32 now.  I considered getting a doctorate in Music Education or Music Performance moreso.  I'm guessing the "Plucky Violin Teacher" is already a great violinist but feels it is best to be good at something like teaching it.  Maybe, most American violinists are subconsciously confused about how they feel about classical music in the USA versus Europe or Germany.  That's probably why they seem so lethargic.  High school's over, and so is college.
