Forgive yourself for anything you think you may or may not have done. Holding onto any of these thoughts holds you back from moving forward. Holding onto regret, remorse or guilt ensures you sit in an unhelpful mind state. Nobody is perfect. Allow yourself that grace, learn from the situation and reflect how you can grow.
