You can use your past to inform you about issues in your life now, but do not obsess over past events.
You need to face up to something in your private life today and to do this you will need to look back and consult with your past. Hindsight is a great thing and you will find answers to present issues in your past. But as events from your past come to the surface do not get bogged down or obsessive about this. These things need to stay in your past.
