It's sometimes easy to look at people, places, and events in our past with a certain amount of derision. We often view them in the lens of how we operate today and dismiss the things of the past too quickly. I am often reminded the past, imperfect as it may be, is the foundation of our present. All of the difficulties, the lessons gained through failure, and our wise & foolish choices have brought us to this point in our lives. To attempt to ignore them completely would negate the building blocks of who we are today. Instead, we can learn from them and choose the correct path as we move forward.
Don't forget your roots. Good or bad, these are what brought you to this point today. What you do with your roots is up to you.
