“Men are disturbed not by things, but by the views which they take of things.”
“Demand not that events should happen as you wish; but wish them to happen as they do happen, and you will go on well.”
“it is in thy power to retire into thyself, and to be at rest”
“love those men whom thy fate it is to live with; but love them truly.”
“our life is short; we must endeavour to gain the present time with best discretion and justice.”
