When the life you've built slips out of your grasp, you're often told it's best to move on. But is that true? Instead of forgetting the past, TED speakers describe how we can move forward with it.

In 2014, Nora McInerny   experienced a wave of loss that reshaped her whole life. Despite the painful memories from that year, she explains why she doesn't want to "move on" from her grief.

In 1994, Lindy Lou Isonhood served on a jury that sentenced a man to death. For years, she agonized over her decision. Today, she says, she's moved forward by speaking out against the death penalty.

At 26, Suleika Jaouad  left the hospital after four years of cancer treatment. But instead of joy, she felt exhausted and broken. She says moving forward sometimes means reckoning with your past.
