I struggle to do so myself so I don't know if that really helps, but maybe meditate, journal, go to therapy, expand your vocabulary on feelings, sensations, emotions. Recognize that the Western civilization is built around making everything sound rational then nothing in our lives actually is. Give yourself the tools to do more introspection so you can recognize your feelings, your needs, your dreams, your fears, your troubles. Don't forget to learn your body, because the mind and the body are not separate at all.
