Worry over what has not occurred is a serious malady.
Your secret is your prisoner; once you reveal it, you become its slave.
Jealousy is cruel as the grave: the coals thereof are coals of fire.
Riches bring anxiety; wisdom gives peace of mind.
Plan for this world as if you expect to live forever; but plan for the hereafter as if you expect to die tomorrow.
The first step in the acquisition of wisdom is silence, the second listening, the third memory, the fourth practice, the fifth teaching others.
