As they say...

Given that all that glitters is not gold and great haste makes great waste, evey one can find fault, [even if] few can do better.

Yet, [at times] one must give the devil his due, even if it's no use crying over spilt milk and even if we let not the pot call the kettle black.

If we accept that it takes [at least] two to make a quarrel, clearly, prevention is better than cure and if speech is silver, silence golden.

Recall that still waters run deep, whereas, empty vessels make the most noise.

Therefore, discretion is [certainly] the better part of valor!
