Is there something from your past that keeps weighing you down and holding you back? If it’s sin, then confess it God, ask him to forgive you, and forget about it. If it’s sin that you have confessed to God and asked his forgiveness for, then forget about it, because God has!
Psalms 103:12 (NLT) - “He has removed our sins as far from us as the east is from the west.”
