If you want to keep something concealed from your enemy, don't disclose it to your friend

My friend is he who will tell me my faults in private.

Your secret is your prisoner; once you reveal it, you become its slave.

As long as a word remains unspoken, you are its master; once you utter it, you are its slave.

Plan for this world as if you expect to live forever; but plan for the hereafter as if you expect to die tomorrow.
