If you're not sure of what to say, don't say anything.
Before a man speaks it is always safe to assume that he is a fool. After he speaks, it is seldom necessary to assume it.
The trouble with talking too fast is you may say something you haven't thought of yet.
You'll regret opening your mouth. You'll rarely regret keeping it shut.
A closed mouth catches no flies.
He who talks much cannot talk well.
Give thy thoughts no tongue.
If you wouldn't write it and sign it, don't say it.
Little said is soon amended. There is always time to add a word, never to withdraw one.
When in doubt, shut up.
If you don't have anything different to say, don't say it at all. That's my rule.
Would the fish have ever been caught if it had kept its mouth shut?
If you have nothing to say for yourself then kindly keep your mouth shut!
