Expressive journaling naturally improves your connection with your intuition.  And intuition can help us make the right decisions for ourselves when we are really unsure of say two choices.  Helping us move towards the life we were meant to live over time.  
Healing traumas can return parts of you back to your true peaceful nature. Making you also more grounded in your empathic nature.
