Do our pasts shape our future?

So many things have happened in my past, and, without a doubt, many important events in your life have already passed you by. No matter how dramatic, or how deserving we were of these things, do they play a role in forming our personality now here in the present? Will events that are currently happening to us make us a different us in the future? They must. The worst must make us stronger and the best must make us happier. Every single moment counted in our lives must help us to be the true us in the end.
