Tomorrow, on the tenth anniversary of the horrific attacks of September 11, 2001, we will mourn the innocent lives lost, honor the heroic first responders who rushed to the scene, and pay tribute to our troops and military families who have served over the past ten years to keep us safe and strong. 

But, I also hope you'll remember how the worst terrorist attack in American history brought out the best in the American people. From giving blood, volunteering time, and donating clothing, food and money, in the weeks and months after the attacks, we were united as a nation, everyone doing their part to lend a hand and help the country move forward together.

With just a small act of service, or a simple act of kindness towards others, you can both honor those we lost and those who serve us still, and help us recapture the spirit of generosity and compassion that followed 9/11.  

September 11th has been designated as a National Day of Service and Remembrance. Americans across the country will come together to honor the victims of 9/11 and to reaffirm the strength of our nation with acts of service and charity. In Minneapolis, volunteers will help restore a community center, in Winston-Salem, North Carolina, members of the community are building new homes for deserving families, and once again, Michelle and I will be joining a local service project as well. 

There are so many ways to get involved, and every American can do something. You can join me in participating in the National Day of Service by finding a service opportunity in your area on Serve.gov. 

A decade ago, our fellow citizens and first responders rushed up stairwells, into flames, and into that cockpit and gave their lives to save others. In the decade since, a new generation -- our military personnel, intelligence officers, and law enforcement -- has stepped forward to serve our country and keep us safe. 

This weekend, I encourage all Americans to remember not only the innocent lives we lost on that day, but to remember the ordinary goodness and patriotism of the American people and the spirit of unity that brought us together during the days and weeks after the attacks of September 11th.  

Sincerely,

President Barack Obama
