Believing in oneself is necessary for personal development and success. It's a thinking adjustment that has the potential to significantly improve one's life. Acknowledging and respecting one's own abilities and talents is powerful. It contributes to a solid foundation of self-confidence. Comparing oneself to others frequently results in unwarranted self-doubt. Focusing on one's progress and accomplishments is a healthier approach to self-development. Visiting prior accomplishments at times of self-doubt may be a powerful reminder of our strengths and perseverance.
