I used to be really nervous when I sang. Like when I was a kid starting young 18 and 19 and my dad really had to sort of push me to start singing in front of people. Ever since I got out there and really started doing it the only thing I've ever tried to do is just sort of is be myself you know never put on a voice. Sing naturally.
The most valuable of all education is the ability to make yourself do the thing you have to do when it has to be done whether you like it or not.
