I think he also uses the 'tell them what you're going to tell them, then tell them, then tell them what you told them' philosophy of information presentation, so when you listen every day, it can start to sound like you've heard this before.

I listen to him every day and never tire of his 'redundancy' because he presents things from a perspective I wouldn't otherwise have.
