This thread makes so much sense
Only speak when it will improve the silence
Only speak when you have something to say that will be of benefit
Always speak in ways that can be understood
Only say it once
Never go on the battlefield; being of benefit isn’t about winning
Avoid wrong speech:
Avoid harsh, mean-spirited or angry words
Avoid falsehoods
Avoid gossip and small talk
Avoid belittling others to raise your own status
