"I've always been a pretty private, quiet kind of person and so I haven't had to change my life really at all, I don't think"

In this quote, Keith Urban is expressing that he has actually always been a reserved and introverted individual. He values his personal privacy and does not feel the need to alter his way of life to fit societal expectations. Despite his popularity and success, he has actually stayed true to himself and has actually not had to make any substantial changes in his life. This might suggest that he is content with who he is and does not feel the requirement to conform to the expectations of others. It also highlights the importance of remaining true to oneself and not letting external impacts determine one's life.
