Here's another question for your life story:
What failures have you had in your life?
This seems like a negative subject to write about, but if you could share what you learned from your failures with others wouldn't it be worthwhile to write about your failures. Sometimes we think everyone else's life is going well. They have a nice home and a beautiful car and a wonderful family. At Christmas I get a few family newsletters from friends who live far away that I don't get to see any more. They describe the family vacation, the successes of their children and the things their family has accomplished in the last year. When my own family is struggling with financial problems, underemployment and unemployment, it can be discouraging to hear about how well others are doing.
When I go to visit someone else and they have a pile of laundry on the couch waiting to be folded, dirty dishes in the sink waiting to be washed, and books or papers scattered across tables waiting to be read or put away, I am encouraged because someone else has a challenge getting everything done too. A spotlessly clean house makes me feel discouraged because my house never looks like that. My life doesn't go perfectly so it is good to know that others don't have perfect lives either.
When writing your life story, don't make it sound too perfect. Share the failures, the disappointments, the discouragements; but also share what was learned and how you coped with it. When others are struggling, they may find hope in what you have written that somehow they can make it through their challenge too.
