NASHVILLE, Tenn. (AP) - First lady Michelle Obama has some advice for some Tennessee high school graduates: strike your own path in college and life and work to overcome inevitable failures with determination and grit.

Mrs. Obama spoke for 22-minutes to the Martin Luther King Jr. Academic Magnet High School in Nashville in her only high school graduation speech this year.

The first lady told the 170 graduates that she spent too much of her own time in college focusing on academic achievements. She said while her success in college and law school led to a high-profile job, she ended up leaving to focus on public service.

Mrs. Obama had this message for the graduates: "Do not waste a minute living someone else's dream."

Mrs. Obama later presented graduate diplomas on stage.
