Will Smith says counselling has helped his marriage work.
The 'Focus' star - who has children, Jaden, 17 and Willow, 15, with wife Jada Pinkett Smith - has admitted the couple have gone for separate therapy sessions but insists it makes them stronger.
He told Access Hollywood: "Everything that you do that's great is gonna be difficult and the most difficult part about a relationship is that it's really not between two people ... it's between you and you.
"What Jada and I have learned is bettering ourselves individually is how you make a relationship work. Individual counselling ... You get yourself together and present yourself to your partner in a higher spiritual and emotional state, and you'll be surprised how much better things can go."
Meanwhile, the 47-year-old actor previously admitted his marriage has been "excruciating" at times.
He shared: "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.
"You can't expect it to be easy. It's like our marriage was the most difficult, gruelling, excruciating thing that we have ever taken on in our lives. And you know we're just not quitters.
"I would say is that we never went into working on our relationship. We only ever worked on ourselves individually, and then presented ourselves to one another better than we were previously."
