Good luck if yoy think that anyone can become a virtuoso on the guitar. I believe you do not really understand what this expression means. And on the singing thing, it's just like playing an instrument, you are born with a baseline hardware (your pipes) and software (your ears). It's a little bit more limited, in terms of how much you can improve from this starting point, than with an instrument, but you can for sure get better through practice.
