If you have a secret and tell someone everyone will know. You can only keep a secret if you don't tell anyone.
If you would not be forgotten, do things worth remembering.
Better slip with foot than tongue.
Take heed of the Vinegar of sweet Wine, and the Anger of Good-nature.
If you have time don't wait for time.
Serving God is doing good to man, but praying is thought an easier service and therefore more generally chosen.
