Paul began his speech as follows: They called Lou Gehrig the iron horse. The tireless worker played an astounding 2,130 consecutive baseball games even though he suffered 17 hand fractures during those years. This would be like one of us never missing a day of school for over 13 years. Can you imagine completing kindergarten through your senior year with perfect attendance? Never taking a sick day, never a college visit day, or even senior skip day. And, to match Gehrig, you would also have to end your school career with an A average. What method for gaining attention and interest did Paul use?

Paul here is trying to get attention of his audience through relating the topic to them in such way that they understand the topic in the est way possible. What Paul is doing here is kind of an analogy , where he is relating the tremendous feats( playing 2130 games , with 17 hand fractures) of Lou Gehrig to completing the school without any leave and scoring A grade, through this kind of analogy Paul would be able to relate the topic to every person in the audience.
