Writing about your life is important because it gives you a chance to reflect. Journaling is one of the main practices that therapists recommend for promoting mental health. It helps people manage anxiety, cope with stress, and deal with depression. When you maintain a journal and you go through your previous entries, you witness your memories without distorting the reality. You see your progress. You remind yourself of the important things you forgot.
The childhood story. Whether your childhood was happy or traumatic, you should include a few anecdotes that give a picture of who you were and what you experienced at the time. You can tell the story of your childhood by breaking it down into smaller anecdotes that illustrate your personality - your parents' reaction when you brought home a stray dog, the time you climbed out of the window at school and ran away for 3 days, your friendly relationship with a homeless person living in the woods . . . get creative.
