From the greatest to the smallest, happiness and usefulness are largely found in the same soul, and the joy of life is won in its deepest and truest sense only by those who have not shirked life's burdens.
It is a curious sensation: the sort of pain that goes mercifully beyond our powers of feeling. When your heart is broken, your boats are burned: nothing matters any more. It is the end of happiness and the beginning of peace.
The activity of God, which is transcendent in blessedness, is the activity of contemplation; and therefore among human activities that which is most akin to the divine activity of contemplation will be the greatest source of happiness.
The way to happiness is: keep your heart free from hate, your mind from worry. Live simply, give much. Fill your life with love. Do as you would be done by.
I feel nothing but the accursed happiness I have dreaded all my life long: the happiness that comes as life goes, the happiness of yielding and dreaming instead of resisting and doing, the sweetness of the fruit that is going rotten.
