When we are no longer able to change a situation - we are challenged to change ourselves.

Between stimulus and response there is a space. In that space is our power to choose our response. In our response lies our growth and our freedom. 

Everything can be taken from a man or a woman but one thing: the last of human freedoms to choose one's attitude in any given set of circumstances, to choose one's own way. 

--Viktor Frankl, author of "Man's Search for Meaning", psychologist, and Holocaust survivor
