Las reglas de Oro de Napoleón Hill

I’m curious whether these lost writings reveal new insights or reinforce his classic success principles. How did the author decide to present these alongside his more famous work?

Some principles felt timeless, but I wonder how well they translate to today’s fast-paced world. Has anyone tried applying these rules recently?

The language felt more personal and reflective here. I’m interested if readers felt it added a new dimension to Hill’s philosophy or if it made the ideas more approachable.
