Does a wise speaker talk down to you or talk over your head as they tell you all they know? Not likely.

A wise speaker does not come across as smarter than you.  The speaker reminds you, often in a new way, of what you already know.  Socrates’ wisdom came by claiming he was not wise; however, his questions showed great wisdom.  As a speaker, relieving your audience’s ignorance is best done by recalling your own confusion and sharing the questions you asked and the answers you found.  But you already knew this, didn’t you?
A wise speaker takes the ordinary and adds a little extra and creates the extraordinary.  Recently, Willasue Susskind gave a speech about a toothpick, a button, and an almond.  By sharing the history of each, the audience saw these ordinary items in a new way.  The little extra she gave these ordinary items made for an extraordinary speech which made the audience wiser.

A wise speaker knows more than they can say.  You are an expert in some aspect of life or at least a serious student.  Whether it is work or a hobby, your interest can make you an interesting speaker.  You lose your audience when you give them too much information.  Wise speakers share enough so
everyone can understand and leave the audience wanting more.

You serve your audience best by turning your experience into wisdom they can use. You can speak wisely by adding a little extra to the ordinary, humbly questioning what you thought you knew and sharing only what is essential to understanding.
