I say what I want to say. If I pay any attention to the audience, this will be called "work".
A few more words just for the sake of it.
Let me use "life is tough" as an example. I heard it in college on a long train ride home from immigrant workers who returned from costal cities to rural countryside, wearing shaddy clothes and eating god knows what; I heard it in a up-scale bar from a self-made billionair who is about to sell another company, sipping fine wine. Do they convey the same aspect of life?
Words can be the same, meaning is different. I think this is probably my point. To me, "many people quote the same thing" doesn't mean anything.
