Have you ever considered this – on a serious note or to humor yourself?
If you could change one thing in your life, what would that be?
What is the ripple effect that could be caused by this alteration?
Are you a different person altogether, or do you see yourself missing out on some memorable events or people in the process?
While there are quite a few movies on a concept like this, The Butterfly Effect caught my attention. Without adding any spoilers, this is one movie you might want to add to your list (with a statutory trigger warning.)
Something worth pondering.
