You will never be the same person today as you were yesterday and when the tomorrow comes there will also be changes within you and how you think. Each day brings us moments of growth no matter how insignificant they might appear, something is learned every day, knowledge is gained even when unnoticed. The events of yesterday could have been harsh but now you can see your strength, sadness could have descended but you have come through and seen a way forward. The only constant aspect of life is the fact that you experience it, grow through it and change hopefully for the better each time you conquer a difficulty or share your experience of happiness.
