Jane Fonda said her biggest regret in life is not knowing how to be a better mother to her kids

• Jane Fonda said she doesn't have that many regrets in life, but she does have one.
• She told CNN that she wishes she knew how to be a better mother to her kids when they were young.

Jane Fonda told CNN's Chris Wallace that her biggest regret in life was not knowing how to be a better parent to her children.

Fonda, after being diagnosed with non-Hodgkin's Lymphoma in September, has famously said she isn't afraid of dying — a sentiment she repeated to Wallace in Sunday evening's interview on "Who's Talking to Chris Wallace?"

"What I'm really scared of is getting to the end of life with a lot of regrets when there's no time to do anything about it. And it's one reason that I try, I'm trying to get it all done before I come to the end," Fonda admitted.

Wallace then asked Fonda whether she has many regrets, to which she responded she does not.

"I was not the kind of mother that I wish that I had been to my children," Fonda said. "I have great, great children — talented, smart — and I just didn't know how to do it."

The actress said her organization, the Georgia Campaign for Adolescent Pregnancy Prevention, has helped her study parenting and realize what good parenting is supposed to look like.

"I know what it's supposed to be now, I didn't know then," Fonda said. "So I'm trying to show up now."

Fonda has three children: Vanessa Vadim with ex-husband Roger Vadim, Troy O'Donovan Garity with ex-husband Tom Hayden, and Mary Luana Williams, who she adopted also with Hayden.

When Fonda was diagnosed with cancer in September, she said she felt "very lucky," because 80% of people diagnosed with this particular type of Lymphoma survive.
