quotes about brevity

Franklin D. Roosevelt:
Be sincere; be brief; be seated.
Gracián:
Good things, when short, are twice as good.
Horace:
Whatever advice you give, be brief.
Mark Twain:
To get the right word in the right place is a rare achievement. To condense the diffused light of a page of thought into the luminous flash of a single sentence, is worthy to rank as a prize composition just by itself…Anybody can have ideas–the difficulty is to express them without squandering a quire of paper on an idea that ought to be reduced to one glittering paragraph.
Mark Twain:
I notice that you use plain, simple language, short words and brief sentences. That is the way to write English – it is the modern way and the best way. Stick to it; don’t let fluff and flowers and verbosity creep in. When you catch an adjective, kill it. No, I don’t mean utterly, but kill most of them – then the rest will be valuable. They weaken when they are close together. They give strength when they are wide apart. An adjective habit, or a wordy, diffuse, flowery habit, once fastened upon a person, is as hard to get rid of as any other vice.
Sophocles:
A short saying often contains much wisdom.
Woodrow Wilson:
If I am to speak ten minutes, I need a week for preparation; if fifteen minutes, three days; if half an hour, two days; if an hour, I am ready now.
