Does it improve on the silence?

"Before you speak, ask yourself, is it kind, is it necessary, is it true, does it improve on the silence?" — Sai Baba

I feel the above quote to be so well stated that it is hard for me to add anything to it that could clarify on its wisdom. So this shall be short and brief. When tempted to fill the silence with words, please consider the question above carefully before you speak. Make sure what you are saying is kind. Be certain that it is something that absolutely needs to be said. Verify that what you are about to say is in fact true and not just a hasty judgment or ego-driven opinion. And finally, assure yourself that it will improve the situation or be helpful to someone or something.
