John Travolta: ‘We Work Hard Every Day’ to Recover from Son’s Death

A year after the tragic death of their 16-year-old son, Jett, John Travolta and wife Kelly Preston say they “work hard every day” on healing – a message reinforced by their recent trip to deliver medics and supplies to earthquake-ravaged Haiti.

“Once you get yourself stable, then you’re able to reach out again,” Travolta, 55, told PEOPLE. “And I think this whole year, every day we’ve been working on stabilizing ourselves. And it’s been successful so far.”

Added Preston: “It helps to look out and be helpful to other people … that really helps.”
