Think not so much of what you lack as of what you have: but of the things that you have, select the best, and then reflect on how eagerly you would have sought them if you did not have them.

Take full account of what Excellencies you possess, and in gratitude remember how you would hanker after them, if you had them not.

The whole universe is change and life itself is but what you deem it - either gratefully better than or bitterly worse than something else that you alone choose.

In an expression of true gratitude, sadness is conspicuous only by its absence

Mark how fleeting and paltry is the estate of man-yesterday in embryo, tomorrow a mummy or ashes. So for the hairsbreadth of time assigned to thee, live rationally, and part with life cheerfully, as drops the ripe olive, extolling the season that bore it and the tree that matured it.
