He wakes up every day with his father's phrase "be useful" in his head

Arnie starts each day by reminding himself the importance of being useful every day like his father preached.

He told People: "It was the very phrase that motivated me.

“I was never looking for closure. I'm not into all this stuff, because I never really blamed my father for anything.

“I never ran around and said, 'It's my father's fault.' It's nobody's fault."
