Learn to admit when you are wrong.
Practice overcoming the shame and regret of your mistakes and, through your words and your actions, you will replace these feelings with humility and courage.
Acknowledging and admitting your mistakes, and trying to do right by those you have wronged, is an investment in your honor, your integrity, and the truth.
It is also an investment in your relationships.
Whatever pain you feel now for amending your mistakes is a raindrop in the ocean compared to the pain you will feel for the rest of your life for failing to do so.
