Anonymous G o placidly amid the noise and haste, and remember what peace there may be in silence. As far as possible, without surrender, be on good terms with all persons. If you compare yourself with others, you may become vain and bitter, for always there will be greater and lesser persons than yourself. Enjoy your achievements as well as your plans. Exercise caution in your business affairs, for the world is full of trickery.
