Brevity

“I do not object to people looking at their watches when I am speaking. But I strongly object when they start shaking them to make sure they are still going.”

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

“It may be observed,   succinctly.”

“Amplification is the vice of modern oratory. It is an insult to an assembly of reasonable men, disgusting and revolting instead of persuading. Speeches measured by the hour, die with the hour.”

“Brevity is the soul of wit.”

“Few sinners are saved after the first twenty minutes of a sermon.”

“But let the wise be warned against too great readiness at explanation: it multiplies the sources of mistake, lengthening the sum for reckoners sure to go wrong.”
