This quote may be a paraphrase of Meditations, Book II:
Since it is possible that thou mayest depart from life this very moment, regulate every act and thought accordingly.
But to go away from among men, if there are gods, is not a thing to be afraid of, for the gods will not involve thee in evil;
but if indeed they do not exist, or if they have no concern about human affairs, what is it to me to live in a universe devoid of gods or devoid of Providence?
But Gods there are, undoubtedly, and they regard human affairs; and have put it wholly in our power, that we should not fall into what is truly evil

“The fans have been really incredible everywhere we've been…. You want to make sure you put on the best concert of your life to show them how appreciative you are.”

Middlebury College Address (2004)
Context: John Lennon wrote a line that I’m sure has been used in many commencement addresses. “Life is what happens to you while you’re making other plans.” … There is really no way of knowing where your life’s journey will take you. I never would have predicted the fabric of my life would have evolved into the rich, complex design I enjoy and am challenged by daily. My work, the achievements for which I am receiving such a great honor here today, my purpose in life, have been born out of a set of unplanned circumstances, in large part, but not completely, circumstances beyond my control. I never anticipated being a caregiver for my spouse at the age of 34. I don’t think I ever dreamt I would help run a foundation that raises money for biomedical research and people with disabilities.
