“One must never despair upon losing something, whether it is an individual or an experience of joy or happiness; everything returns even more magnificently. What has to decline, declines; what belongs to us, stays with us, for everything works according to laws that are greater than our capacity for understanding and that only seem to contradict us.”
~The Poet’s Guide to Life (Translated by Ulrich Baer)
The Rainer Maria Rilke Archive 
The passing and experience of people, places and things that affect everything that we do and how we portray ourselves to others. The experience or people we have met in our lives affect each person differently and therefore affect how we carry ourselves into the future. I carry some regrets and some I do not but the past is the past and we must all concentrate on the future ahead 🙂
So very true! Everyone walks this life with experiences, both good and bad, it’s how we carry it and move forward that matters. 🙂
