Matthew McConaughey knew early in life that he wanted to be a father.

When speaking about the book on “Good Morning America,” he explained the story of when he aspired to fatherhood.

He continued: "In my 8-year-old mind, what I noticed at that time, was every man that I had said 'sir' to -- the common denominator was they were all fathers, and I remember saying, 'That's when you've made it. That's when you've succeeded in life, when you become a father.'"

"From that day on it was very clear to me the one thing I knew I always wanted to be," the “Dallas Buyers Club” star added.

McConaughey and his wife Camila Alves have three children -- Levi, 12, Vida, 10, and Livingston, 7.

The couple has been married since 2012. They met in 2006.

The actor recalled the first time he laid eyes on Alves, 38 

"I can't say I knew she was the one," McConaughey told the outlet. "I will say this, she was moving to my right-to-left across a room, and it did not look like she was walking, meaning her head was not bobbing. She was more floating, and I did not say, 'who is that?' -- I said, 'what is that?'"
