It encourages you to listen to ideas that make you think hard, not just the ones that make you feel good, and to surround yourself with people who challenge your thought process, not just the ones who agree with your conclusions.
Te anima a escuchar ideas que te hacen pensar a fondo, no solo las que te hacen sentir bien y a que te rodees de gente que reta tu proceso pensativo, no solo de quienes concuerdan con tus conclusiones.
