Results are nothing; the energies which produce them and which again spring from them are everything.

Happiness is so nonsynonymous with joy or pleasure that it is not infrequently sought and felt in grief and deprivation.

I am more and more convinced that our happiness or our unhappiness depends far more on the way we meet the events of life than on the nature of those events themselves.
