McConaughey and his wife Camila Alves welcomed their son, Livingston, into the world three weeks ago, joining their two other children, four-year-old son Levi and daughter Vida, 3, reported E! Online.
"When you have got a family, you have to pick your extra-curricular. Whoever has kids knows that. You have to pick and choose and go wait, which is the one I really want to do because I ain't watching all the Saturday's football and I am not watching all of Sunday's.
"I am not going to be a kayaker, a snow skier and a marathon runner. No, you gotta zero in when you got kids and a family," he said.
Talking about direction plans, McConaughey said he has no desire to ever move behind the camera as he is satisfied with simply being an actor.
"I am really enjoying being an actor for hire. I have been offered to produce some things and I've said, 'No thank you.' I am really enjoying my time getting ready for a role, my man, my characters, going to work, doing my best to nail it, finishing work and going."
