The centennial of John F. Kennedy’s birthday is Monday, and in an early Memorial Day tribute, his daughter and grandchildren reflected on the life of the 35th president and the impact he had on their lives.

At the start of a video created by the JFK Library, Caroline Kennedy said she has thought about her father "and missed him every day of my life," Today reported.

“Growing up without him was made easier by all the people who kept him in their hearts, who told me that he inspired them to work and fight and believe in a better world, to give something back to this country that has given so much to so many,” she said in the video.

Kennedy, 59, recalled hiding under father’s desk in the Oval Office, and spoke about the generation her father inspired, Today reported.

"As my father said in his inaugural address, 'This work will not be finished in our lifetime, it's up to us to continue to pass these values on to our children and grandchildren,'" she said.

In the video, Tatiana Kennedy Schlossberg spoke of her connection to her grandfather, then described her unique connection to one of the nation's most historical figures.

"One of the defining relationships of my life is with someone I've never met, my grandfather, President John F. Kennedy," she said.

“To me, that is where he lives, as a historical figure rooted in the past, but also as a person connected to so much of what came after him,” she said in the video. “But while my grandfather had reverence for the past, and the lessons it could impart, he also knew that America was a country where change was possible. That we aren't bound solely by tradition if we understand the past with which we are breaking."

Tatiana's sister, Rose Schlossberg, also described the need to reflect upon the past to help shape the future.

"My grandfather would be proud of how far we’ve come as a nation since 1963, but he’d have been the first to tell us that we have a long way to go,” she said.

The president's only grandson, Jack Schlossberg, said his favorite speech by John F. Kennedy was about sending a man to the moon, "not because it would be easy, but because it would be so hard."
