Don't Cry Over Spilt Milk.

We Should Use Our Judgment Before Coming To A Decision.

Better To Learn Wisdom From Other People's Misfortunes Than From Your Own.

It Is With Our Passions, As It Is With Fire And Water, They Are 'good Servants,' But 'bad Masters.'

Zeal Should Not Outrun Discretion.

Forbear Harping On What Was Of Yore, For It Is The Common Lot Of Mortals To Sustain The Ups And Downs Of Fortune.
