Tom Cruise and Katie Holmes review their marriage every day
The couple - who have a four-year-old daughter Suri - always try to learn from their mistakes and consult each other on how to correct their errors.
Tom - who has previously been married to Nicole Kidman and Mimi Rogers - explained: "Because we do live in a cynical world, it`s easy to be cynical. Making the choice not to be cynical is important. You can keep dwelling on what didn`t work, or you can figure out how to fix it.
"You know, I`m married to such a special woman. Every night before we go to sleep, Katie and I look at each other and it`s like, -How`d we do today?- "
As well as his close bond with Katie, Tom - who attended 15 schools in 12 years - has a strong attachment to his three sisters as he had few friends growing up and they encouraged his love of acting.
He explained in an interview with America-s Esquire magazine: "You hear about people who have lifelong friends. I never was in a place long enough to have them. So that role was filled by my family.
"If anyone was teasing my sisters, I really felt it... I`d create different characters and ad-lib sketches to make my sisters and my mother feel better. I`d try to make them laugh.
"I`d do Donald Duck as John Wayne. I`d watch -Soul Train- and imitate the dancers. I guess you can say that`s where it started. I always had a dream to be in movies, my family didn`t say, -That`s impossible-. They laughed."
