The author connects reading Shakespeare to the personal self-interest of his audience by relating it to<em> how a person learns his subjects in school</em> or <em>how he learns a piece of music.</em> He further emphasized that if a person tries to <u>read Shakespeare again and again, he'd be able to grasp the meaning of his writings.</u> This is similar (as he stated) to that of listening to a piece of music for the first time. People, sometimes, don't get the meaning of the song at first but later on, appreciates it. If a person wants to know Shakespeare more, reading his writings over again is worth the effort.
If a person doesn't try, then he'll never learn, thus reading Shakespeare is a<em> personal interest</em> and is dependent on <em>open-mindedness to possibilities.</em>
