Calling your mother more often might not change what happened ten years ago on September 11th.

But a group of people believes good deeds like that can help change the course of events from this day forward.

More than a thousand committed to acts of good deeds today in honor of 9/11 victims.

The annual "Good Deed Mitzvah Marathon"on the University of Florida campus was sponsored by the Lubavitch-Chabad Jewish Center.

Participants wrote their good deeds on a card, then attached it to the picture of a 9/11 victim.

The picture and card were then placed on the "Twin Towers of Good Deeds and Love" a cardboard replica of the Twin Towers.

The pledges included actions like taking care of a sick roommate, tutoring a child, giving blood, calling grandparents more often, and simply committing to not judge others
