Every time you are tempted to react in the same old way, ask if you want to be a prisoner of the past or a pioneer of the future.
Our reactions often feel automatic, but most of them are habits we learned long ago. When someone criticizes us and we bristle, or a conflict begins and we go silent, we are usually replaying an old script written by earlier experiences. The quote suggests that each of these moments is a fork. We can let the past decide for us and remain its prisoner, or we can respond to what is actually in front of us and help create something new.
This fits the themes Chopra is known for: the influence of the mind on the body and daily life, and the idea, drawn from Indian Vedanta and meditative practice, that awareness opens a gap between impulse and action. In that gap we have a choice. The quote is widely attributed to him, though I can't point to the original source.
Imagine someone who always gets defensive when a colleague questions their work. Next time, they might notice the tightening in their chest, take a slow breath, and ask a curious question such as "What would you change?" That small pause is a step toward a different future.
