Think about those times when you would say to yourself, "If I had a chance to go back, I would change/fix this". We always remember moments in our lives where we later on realize that if we had made a better choice or pursued a better action then, life may be a little different now. But every experience we had is a apart of our growth and development. Look at what you know now because of what was done then. Embrace your experiences and learn from them. Once you learn the lesson(s), apply them to your life now and see how much better each day is because of what you have learned. Don't punish yourself for your past. Embrace it and don't be ashamed of it. Your past is what is going to propel you into your purpose! Continue to live each day better than the day before.
