The only difference is he is talking about playing guitar and we are talking about being yourself. Vai speaks of a vision for your playing, we speak of a vision for you and your life.
He talks about your practice space and we talk about every moment of your life. Otherwise, we are in perfect agreement with him. Practice being your most genuine self. Don’t wait for the right job–be the right person practicing your career song.
The piece is 7 minutes–well worth it.
