Though thou be destined to live three thousand years and as many myriads besides, yet remember that no man loseth other life than that which he liveth, nor liveth other than that which he loseth.

Don't let your imagination to be crushed by life as a whole. Don't try to pictures everything bad that could possibly happen. Stick with the situation at hand. ...Then remind yourself that past and present have no power over you. Only the present.

Leave other people's mistakes where they lie.

Do not indulge in dreams of having what you have not, but reckon up the chief of the blessings you do possess, and then thankfully remember how you would crave for them if they were not yours.

A good disposition is invincible, if it be genuine.
