I had a brief exposure to guitar with a couple lessons in grammar school (age 12). After that, Music went dormant in me until I wondered into a music store at age 40, rented an acoustic guitar and signed up for lessons. That was 25 years ago and since that time, the flame has kindled, simmered, burned hot and flickered at bit at times, but never gone out.
So, since you have defined 'made it' as intentionally vague, while you have likely never heard of me, I do put myself on the list.
