You know what. If you really think about it this man knew the mind of most artists.
He knew that most of us lack a lot of self confidence and are scared of making mistakes and so on. He knew that those fears are the ones that keep us from grown and becoming better artists. He knew that if we focused in the good we would keep moving forward without ever looking back or dwelling on our mistakes.
That or I’m over-thinking it. :0
