Who would you be without your history?
Can you imagine who you would be, how you would think and behave if you woke up one day and couldn't remember a thing from your past?
(Presuming you would still know how to walk, talk and most things you know.)
Are there experiences you'd be happy to let go?
Are there elements of your past that you would be sad to forget? Even difficult times, would there be things you wish you could still remember, to know you survived?
If there are things in your past that you wish you could change, is there any way you could come to peace with those today? Can you think of any words or actions that could change something in the present?
