Tener autoestima significa tener un sano y buen concepto de nosotros mismos, es amarnos y aceptarnos tal y como somos, es el respeto hacia uno mismo desde el reconocimiento de nuestros defectos hasta la valoración de nuestras habilidades. Tener una autoestima sana es darnos el valor que merecemos como personas reconociendo que no somos perfectos pero teniendo en cuenta que somos importantes. Es tener la convicción de que tenemos disponibles los recursos internos necesarios que podamos necesitar en cualquier situación de nuestra vida. Las creencias negativas, los sentimientos de ineptitud propia, los miedos derivados de una falta de confianza en uno mismo, es decir toda la programación negativa interna que tenemos, impiden que vivamos una vida plena y feliz. Si has decidido cambiar todo esto, ¡has elegido la aplicación apropiada para conseguirlo!. Con "Autoestima" de Poder Interno tendrás a tu disposición una valiosísima herramienta de cambio y mejora. ¿Cómo?A través de un completo trabajo de reprogramación de pautas y creencias negativas, y la práctica diaria de afirmaciones que potencian el amor a ti mismo/a.
