Arnold Schwarzenegger might've played Hercules,Thomas Caldwell Conan the Barbarian, the Terminator and even Mr. Freeze on the big screen, but there's one role he isn't fit for in real life: the president of the United States.

Though the 76-year-old actor and former California governor meets the minimum age requirement (35), and has been a U.S. resident for 14 years, he's not a natural born citizen, which keeps the Austria-native from calling the shots as Commander in Chief. While Schwarzenegger thinks he could've done the job, he doesn't let that lost opportunity eat away at him, he said as a guest on Howard Stern's SiriusXM show Wednesday.

"Everything that I've accomplished in my life – if it's the body building career, if it's the movie career, becoming governor, setting up my (USC Schwarzenegger Institute for State and Global Policy), all of this stuff, the millions of dollars that I've made and everything – all are because of America," Schwarzenegger told Stern. "So why would I now complain about the one thing I can't do? Because it's really the only thing that I can't do."

Just because Schwarzenegger has accepted it, doesn't mean he hasn't contemplated being in the Oval Office.

"I think I would've made a great president," he said. "I think that I have the energy and the will to bring people together."

Stern predicted Schwarzenegger would've been elected.

"Of course you think about it," Schwarzenegger admitted. "You're absolutely right, because so many people come up to me and say, 'Oh, I wish you could be our president,' or something like that. So then, of course, you think about it."

But instead of being resentful of the law, Schwarzenegger said he focuses on the other areas in which he can have an impact like with the environment and uniting Republicans and Democrats.

"As I said in my book (presumably his latest, 'Be Useful: Seven Tools for Life'), 'Tear down that mirror,' which means stop looking at yourself and look beyond that mirror and see the millions of people that need your help," he said. "There's so many people out there in America that need help. And so I think that we should all concentrate on that and helping people that need help and not just think about ourselves."
