“say what you mean and mean what you say”
“there are many kinds of sincerity and insincerity. When you say 'thank you' for the salt, do you mean what you say ? No. When you say 'the world is round,' do you mean what you say ? No. It is true, but you don't mean it”
“Say what you think; think what you mean.”
“You've got to say what you mean and mean what you say...Doubt in your voice is an open door people will shove right through.”
“Say only what you mean.”
“People say exactly what they mean when they are angry. That's when they are the most free to do so. They may not mean to hurt you, but they always mean what they say.”
