The past is a choice. In so many ways, the decisions you made in the past define you today. But you can move beyond them. The decision to stay with past choices and past decisions is completely your own to make.
You can, if you choose to, stay with the decisions you made and let the ripples of them define who you are today, or you can decide that this is not who you want to be anymore and sever your ties to past events and choose a new starting point from which to define your life.
Your past, of course, will always be there. You cannot magically erase from where you came from. You can though, choose what to emphasize. You can choose what you want to build from to define who you are today.
