When we choose to live according to our truth, we are true to ourselves. Then, to be true to yourself means you listen to your inner wisdom and follow it. You live with integrity. You pursue your dream(s).
Sometimes we repress who we are and live our lives according to the expectations of others to please them. A person may change a hairstyle or color because of peer pressure. A young man who does not want to work in his father’s business does not pursue his dream of becoming a lawyer or a doctor.
