Another benefit of journaling from Beth's benefit's list: Access your creativity.
I think this one is my favorite since I know how vitally important it can be to have our creativity as a priority in life. I know when I engage in something that validates who I am, as an artist and individual, expressing myself, that my health benefits. Art is Healing. So I journal about my art a LOT and keep myself accountable to stay with it and make it priority.
