Your boldest self emerges through the experience of having full access to your values, traits, and strengths and knowing that you can autonomously and sincerely express them through your actions and interactions. That is what it means to believe in your own story. In essence, self-affirmation is the practice of clarifying your story to yourself, allowing you to trust that who you are will come through naturally in what you say and do.
