Even with an Academy Award nomination and two Primetime Emmy Awards under his belt, William H. Macy doesn't feel secure in his success.
"I think at the heart of every actor is a little voice saying it's a fluke and it's going to go away any moment, and I'm no different," the 66-year-old actor told CNBC.
Despite his self-doubt, Macy has succeeded in multiple capacities. He received an Oscar nomination for Best Actor in a Supporting Role for "Fargo." He won two Emmys in 2000 — for acting and writing.
