Will Smith and Jada Pinkett Smith: Perfect Parents?

They have a marriage business plan.

"If you don't have a purpose for your relationship, if you don't have a place that you're going, something that you want to accomplish, something that you want to do, you can really get lost in the murk of the journey," Will says. "There has to be a vision. Like, why are we together?"

Will's ex-wife Sheree and Jada get along for the sake of the child.

"Sheree and I both had to make that decision, because at the end of the day, we had Trey and that had to be the primary focus," Jada says. "So we had to put aside our own craziness, our stuff, all the baggage that comes with it. She and I just had to focus on, 'What does he need?'"

The goal for the children is for them to be their best selves.

"I just want them to live in service to greatness. I want them to live and to create in a way that when people see it, people are inspired and people become better just by having contact with their excellence," Will says.

They let their kids define their own greatness.

"We might have a vision for what we see, but at the end of the day, Jaden has to have his own vision, Willow has to have her own vision and so does Trey," Jada says. "So we are there to help inspire and facilitate their vision, because in order to reach the type of excellence that Will is talking about, you have to be able to reach inside yourself to find that drive. Nobody can put that drive in you, so you have to inspire the individual to find and focus on the goal that they want for themselves.

They're raising grounded children in Hollywood.

"I tell them all the time: 'Mommy and Daddy are rich. You all are broke,'" Will says. "We don't allow them to just sit around. We talk about the concept of the group and the necessity of you adding to the family. Then you have to add to your neighborhood, and then you have to add to humanity."

They don't punish their kids.

"That's one of the really difficult struggles because we don't exactly believe in punishment, per se. We believe in restriction, that you can have as much freedom as you can handle," Will says. "You can cut your hair. You can put stuff on your wall. And as soon as you do something that is detrimental to yourself, and when you can't be trusted with your freedom, then you have to be pulled back. But it's not about punishing you for what you did? It's about protecting you from the potential damage that you could do to yourself."

Will traveled home from China every weekend during The Karate Kid shoot to see Trey's football games.

"It's really important," Will says. "When I grew up, that's how it was with my parents. It's like they were showing up at all the stuff and I just felt like, you know, you have three children and it's dangerous to play favorites or lean one direction or something like that, and it was just hugely important. He had to know his father, even though he doesn't really know how long the flight is and all that, one day he's going to take a flight back and forth a couple of times and he has to know that his father flew home to be at his football games every week."

They keep things spicy in the bedroom.

"To keep it spontaneous, I surprise him because he's a thinker," Jada says. "He's always in his head. I always surprise him. During the day, I might send a sexy picture of some sort. Just a reminder of what's waiting at home. And if he's on the set with me, on the set of 'Hawthorne,' he might take a little break."
