I know how to treat my voice to make it sound as good as it possibly can - which is still not that good.
Playing gives me as much good feeling now as it did when I was a bitty kid.
My very, very first professional job was when I was 19 years old - I got a job doing an educational industrial film on Shell Motor Oil's oil products. I really put my heart into it - I wrote a script for it, I did a lot of research.
