I am borrowing this from David Ogilvy. (because it makes perfect sense)
If you want ACTION, don’t write. Go and tell the guy what you want.
Tell the guy.
SPEECH, not writing, is still man’s primary form of communication. Print, in all its forms, whether “texting” or “posting” or newspaper advertising or whatever, is still just an approximation, an imitation, of human speech.
Words well chosen, especially when spoken, have a unique power to compel to action.
