8 powerful life lessons from 93-year-old Norman Lear, one of the most influential people in TV history

That's why Oscar-nominated directors and producers Heidi Ewing and Rachel Grady are exploring the lasting effects of his career in their new documentary "Norman Lear: Just Another Version of You."

Lear is the creator of shows like "All in the Family," "Good Times," and "The Jeffersons," programs that not only brought in 120 million viewers a week, but challenged Americans' views on topics like racism, poverty, and abortion.

He's one of the first group of inductees to the Television Hall of Fame and has four Emmys and a Peabody Award, among many other honors.

Today, Lear is 93 years old and as sharp as ever. He spoke with Business Insider last year about his 2014 memoir "Even This I Get to Experience."

Drawing from that interview and his book, we gathered the life lessons that have stuck with Lear after all these years.
