The CAS “attitude” is captured beautifully in John Hall’s poem.

“Real Evaluation”

Is anybody happier because you passed this way?
Does anyone remember that you spoke to him today?
The day is almost over, and its toiling time is through;
Is there anyone to utter now a kindly word to you?
Can you say tonight, in parting with the day that’s slipping fast,
That you helped a single person of the many that you passed?
Is a single heart rejoicing over what you did or said?
Does the person whose hopes were fading, now with courage look ahead?
Did you waste the day, or lose it? Was it well or sorely spent?
Did you leave a trail of kindness, or scar of discontent?
As you close your eyes in slumber, do you think someone will say,
“You have earned tomorrow by the work you did today?”
