Boosting your self-confidence starts with being kind to yourself—swap self-criticism for affirmations and set realistic goals to celebrate your achievements. Take care of yourself with exercise, good food, and rest, and wear clothes that make you feel great. Stand tall, make eye contact, and practice open body language to show confidence. Learn and grow in things you love, and surround yourself with supportive friends who cheer you on. These steps can help you feel more confident in yourself every day.
