If you ask people what matters more, deep thought or how it sounds. They’ll say thought is more important. But they always lie. For example, I like Rammstein but don’t know German words. So they can sing about bad things, and I’ll still like Rammstein. In this case, the ‘quality of thoughts’ doesn’t play any role. Because people care HOW it sounds. So, for your speeches, you need to figure out one key thing: People will remember HOW you talk, NOT what talk.
