How do we move on from 9/11?

When we think about 9/11, we often only think of the tremendous loss of life on that day. But what we sometimes forget about are those who made it; the thousands of people who survived the attacks, but have had to carry it with them every day since. 

Firefighter Jay Jonas and Port Authority Police Officer Will Jimeno were in the Twin Towers on September 11 — 100 stories of the World Trade Center fell on top each of them. But they got back up and survived.

How did they move on from this attack? And how should we?
