The 32-year-old, who is currently dating model River Viiperi, says she is no longer interested in fame since Nathan Lee Parada tried to break into her LA home wielding a knife in August 2010, reported Contactmusic.
She is now determined to follow her family's footsteps in hotel business.
"It was terrifying. I had never experienced anything like that before and it really shook the foundations of my world. I was certain he would kill me if he could get inside.
"Seeing someone with such hate in their eyes. Someone who wants to kill you makes you question things, and it made me wonder about the price of fame. There was so much chaos in my life at the time. After the attack I decided it was time to withdraw from the public eye before anything worse happened," Hilton said.
Hilton said she is inspired by her grandfather who created the successful business empire from scratch.
