Healthy food and plenty of exercise. The challenges military families face. Education for girls around the globe.

The feel-good initiatives of first lady Michelle Obama have served as both inspiration and eight years of teaching moments for many families. So what, exactly, do they think is her legacy over a period that spans much of the lifetime of today's kids?

"I think she stands for kindness in America," said Alexis Shenkiryk, a 12-year-old in Del Mar, California. "She really encouraged me to try harder, and she promoted a lot of good things for everyone, not just certain people."

Inara Abernathy, a 17-year-old in Nashville, Tennessee, has absorbed many life lessons of her own from the first lady.

"She's strong and beautiful and she makes me feel beautiful, too," Inara said. "I feel like I can accomplish things when I think about her."

Then there's bullying.

"I was bullied a lot when I was little and she taught me how when I got bullied to just don't think about it," Inara said. "Ignore them. Live your life and be happy."

Her dad is a retired Army colonel and the teen admires Obama's shoutout for military families. And when the first lady put in the White House garden, "it made me think about eating better food and losing weight," Inara said. "Without her, I'm not sure I would have done that."

Norfolk, Virginia, 10th-grader Kassidy Carey canvassed for Hillary Clinton and has volunteered to advocate for various social causes through the site DoSomething.org. She was too little to remember the president's first inauguration, but she loved watching the second one. She's a regular first lady watcher.

"I really appreciate that the first lady tries to make young girls feel like more than just girls, you know," said Kassidy, who plans to study law. "She makes us feel like people who actually have opinions that matter and who can fight for what we believe in."

Kiki Emordi is 8 and in the third grade in Richmond, Texas, outside Houston. Her parents are originally from Nigeria and her mother, Ngozi Emordi, teaches English.

"She's a bold woman," said the elder Emordi, who also has two older girls and a son. "Any black girl can just see Michelle and know she can dream big. She says to these girls it doesn't matter where you come from or what you look like, you can be anything that you want to be."

Lesson learned, as far as Kiki is concerned. She is forever on the hunt for any news of Obama, whether it's about a fresh speech or fabulous outfit.

"I really look up to her as a role model," she said.

At 7, Jordan West of Rochester, New York, helps her two older brothers run the family's Champions of Change, a nonprofit they started to urge young people to become "change agents" in their communities.

"One of her goals is to help little girls," said Jordan, who was inspired by the first lady to do the same.
