Los Angeles: Will Smith has been married to Jada Pinkett since past 20 years, but the actor says marriage has been the most difficult and gruelling decision they have ever made.
The 47-year-old actor said it takes a hard work to keep the bond intact but they are "not quitters," reported Aceshowbiz.
"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. 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. And you know were just not quitters," Smith said. "If there is a secret I would say is that we never went into working in our relationship.
We only ever worked on ourselves individually, and then presented ourselves to one another better than we were previously," the "Concussion" star added.
