After being sober for four years, Jessica Simpson is ready to discuss her journey. 

Simpson, 41, shared in a new cover story with Entrepreneur that her subconscious played a major role in both her personal and professional life. 

"When I stopped drinking, it was because I had stopped hearing the voice I really trusted, and I was lost without her," Simpson told the outlet.
