Happiness and freedom begin with a clear understanding of one principle: Some things are within our control, and some things are not.
If thy brother wrongs thee, remember not so much his wrong-doing, but more than ever that he is thy brother.
He who laughs at himself never runs out of things to laugh at.
Control thy passions lest they take vengence on thee.
Don't be prideful with any excellence that is not your own
He is free who lives as he wishes to live; who is neither subject to compulsion nor to hindrance, nor to force; whose movements to action are not impeded, whose desires attain their purpose, and who does not fall into that which he would avoid.
