The power of speech:
Words are powerful.
Soothing words can heal people. Mean- spirited words can kill people.
Words from a revolutionary can change the world.
Words of a despot can destroy the world.
And words are free, all you have to do is to use them well.
Speak clearly so people can hear you. Choose your words carefully so people are impacted by you. Choose your tones and rhythm carefully so people remember what you say.
