Matthew McConaughey's 94-year-old mother enforced one strict, unwavering rule while raising her three sons.
She required her children to uphold the household standards for as long as they lived at home.
"Once you hit 18, you are out and free to live as you choose," Kay McConaughey explained.

Kay McConaughey, mother of actor Matthew McConaughey, reveals the one parenting principle she never wavered on during her sons' upbringing.

"Be consistent," the 94-year-old told Southern Living in an interview released Saturday. "Lay down the rules and state, 'This is how it is. No debates. Period.' Consistency is everything."

Born Mary Kathlene McCabe, she and her late husband, James McConaughey, raised three sons.

"I nurtured three boys into loving and productive men," she said, emphasizing that compliance with her guidelines was mandatory under her roof.

"They had until age 18 in my home, with one clear rule - you obey me and follow my lead," McConaughey stated. "After 18, you are gone and can do whatever you want."

She believes the core lessons she imparted guided them long after they left.

"They turned out great because the values I provided became their foundation once they ventured out," she added.

Kay McConaughey is among celebrity parents who have opened up about the principles they prioritized in raising their famous children.

"All those hard times my father pushed me through as a kid served a purpose. When career setbacks hit, I knew to dig in and grind," Beckham reflected.
