Trust what you hear inside.  Yes, of course, at times they may be your thoughts, born of your unique belief system and experiences, but at other times the words you hear are insightful beyond your normal thoughts.  From where did those come?  There is ultimately only One Mind, one Sea of Consciousness from which all thoughts bubble to the surface.  As these thought-bubbles arise through the more tumultuous waves of the human mind, they become a bit distorted and shaped to match your individuality.  It is the ones that stand out for their uniqueness, unshaped by what you know as “my” mind that, once truly noticed, may lead to genius and breakthroughs.  You are so very loved
