Say it again and again (Shout)

I was reading Tom Peters blog (yes that's my daily dose)...

I figured out that there are few things that he believes and is passionate about...  And these things he says again and again and again... As if he shouts from top of his house at the top of his volume...

I feel that he believes very very strongly in his thoughts and thus just shouts and shouts the same thing... pleading people to understand and to make a difference.......
