Use your past for more prosperity and not for more misery

I'm currently writing a book about things I've been through and as a result I've been reflecting upon that so many people seems to dwell in their past to understand why they feel like they feel today. We use our stories of the past as an excuse or reason to our current situation instead as a method to get insight and change current state of mind. This is a talk about the difference and how it have helped me to heal.
