Will Smith talked about his marriage to Jada Pinkett Smith, admitting that it was not easy. "You can't expect it to be easy, it's like our marriage was the most difficult, grueling, excruciating thing that we have ever taken on in our lives," he said.

"We've been married 20 years and we've been asking ourselves [what's the secret to marriage] and really at the end of the day it's just not quitting," the actor explained to Entertainment Tonight. "And you know were just not quitters."

"If there is a secret I would say is that we never went into working in our relationship," the "Concussion" star added. "We only ever worked on ourselves individually, and then presented ourselves to one another better than we were previously."

In a separate chat with The Hollywood Reporter, Will revealed that he might enter politics one day. "They might need me out there," he said. "This is the first year that I've been incensed to a level that I can't sleep, you know? So I'm feeling that, at some point, in the near future, I will have to lend my voice to the conversation in a somewhat different way."

"At this point, I'm elevating my ability to be useful in the world," he continued. "I think that that's what my grandmother always hoped, that I would make myself useful to people in this lifetime."
