Most of us have stories in our past we’d like to forget.
Don’t.
Get the best story you can out of the experience. The best stories are cautionary tales anyway; learn a lesson. Pass it on. Let someone else benefit from your pitfalls, and bond a little while you’re at it. You don’t have to feel shame just because you had a long road to get to the person you are today. As long as you’re on that path, you should be proud.
