It's funny, I don't remember a time that music just hit me. It was always just there for me. I even remember being 4 or 5 years old staying over at a friend of my moms, sleeping in the living room and, for whatever reason, the stereo in the living room was on all not (though low volume). I remember waking up around 2AM and being transfixed in the darkness. Johnny Cash' version of 'Ring of Fire' was played and I had the imagery of a ring of fire in my head (since I was four-ish...it was a literal ring of fire!). So, I guess it was just always there. I don't remember a time when I wasn't moved by it.
I did, for a handful of years become, as you said, a bit of the 'thrill is gone' person. I was in the business and worn out (by in the business, I was on the selling side and not making side).
When you live it everyday, it can drain you.
I got out of the business and started playing again...so, here I am.
