Tonight on "The Kelly File," Charles Koch sat down with Megyn Kelly for a rare interview.

Koch said that his new book, "Good Profit," encourages people to try new things, experiment and not be afraid of failing or making mistakes.

"If you never fail, then you’re probably not doing very much," Koch said. "You’re certainly not innovating, you’re not improving, because the only way you improve is to try new things."

He explained that success is actually one of the worst enemies of success, because it tends to breed complacency and lack of humility.

As for President Obama's criticisms, including the claim that, "The Koch brothers are trying to prevent new clean energy businesses from succeeding," Koch said that the opposite is true.

He said it's beneath the dignity of the office for the president to misrepresent what a company stands for and to attack private citizens for trying to help people improve their lives.

Koch said it's things like that that are why he's not fond of politicians and only recently got more involved in politics.

"I don’t think politicians are going to reverse the trajectory of this country. I think it’s going to depend on the American people understanding what is fair and what makes their lives better," Koch said. "I want the power to go back to people making decisions over their own lives, rather than some experts making it."
