It's quite simple, (public speaking) Say what you have to say and when you come to a sentence with a grammatical ending, sit down

Say what you have to say and the first time you come to a sentence with a grammatical ending-sit down.

A good speech should be like a woman's skirt; long enough to cover the subject and short enough to create interest.

If you have an important point to make, don't try to be subtle or clever. Use a pile driver. Hit the point once. Then come back and hit it again. Then hit it a third time - a tremendous whack.

Ending a sentence with a preposition is something up with which I will not put.

I got into my bones the essential structure of the ordinary British sentence-which is a noble thing.
