You may not realise that holding onto past regrets and strong emotions such as anger, sadness, resentment, and so on, can hold you back from moving forward. These feelings can produce a very strong cocktail of emotions, which can act as an anchor, anchoring you to your past. This in itself will inadvertently hold you back from truly living your life.
Your focus will look inward and to the past, and you will drift through your day consumed with a preoccupation with what has been. The past cannot be changed and until you decide to forgive and let go, this will affect you emotionally and impact on your physical health.
An inward focus means you will not be looking ahead, to future possibilities.
Make a choice, free yourself, choose to let go of the past and move forward.
