My favorite bit about that is attributed (on Google) to guru Sai Baba:
“Before you speak, ask yourself: Is it kind, is it necessary, is it true, does it improve on the silence?”
If we could all just remember this …
Before you publish a post, reread your post, and ask yourself these questions. Before you send that comment, reread your comment, and ask yourself these questions.
If the answer is ever anything but an unequivocal “Yes”, then choose silence.
