Michael Douglas has revealed that he took his actress wife Catherine Zeta-Jones "for granted".
The 69-year-old actor said that he learnt from his past mistakes after temporarily splitting from his wife last year, reported Digital Spy.
"When you are younger you care what other people think. And you take the person closest to you for granted. You waste a lot of energy on strangers to make a good impression. When you're older you focus that energy on the people closest to you, on your family. And you're courteous," he said.
Douglas also explained that he thinks mistakes are only bad if people fail to learn from them.
"First you have to admit that you made a mistake, then dealing with it is easy. Of course it's important to make mistakes, as long as you grow from them," he said.
