People who’ve experienced a ‘once in a lifetime’ event, what was it and how did it change your perspective on life?

We had a “once in a lifetime” honeymoon. Travelled to India, Bali, Indonesia and Australia. We may visit these places again individually but we will never get the chance to recreate the time we had on our honeymoon again. It opened my eyes culturally. Every adventure we had, every food we tasted. I took so much value from that trip.
