Arnie feels "much wiser" than he's ever done

The former politician has learned to "think more about people" and has never felt "wiser or smarter".

He told People: “So today I feel good where I am. I feel I'm much wiser. I'm much smarter. I'm not as crazy. I think more about people. I think more about people's feelings. In your 20s, you don't do any of that. It's me, me, me, me. As time goes on, you learn from your mistakes.”
