“a setback is a setup for a comeback”

It – How Churches and Leaders Can Get It and Keep It (2008, Zondervan)

Campaign rally, Madison, Wisconsin, CSPAN: Campaign 2008 (18 February 2008)
2000s
Context: What we've learned over this year is that hope is making a comeback. It is making a comeback. And let me tell you something — for the first time in my adult lifetime, I'm really proud of my country. And not just because Barack has done well, but because I think people are hungry for change. And I have been desperate to see our country moving in that direction and just not feeling so alone in my frustration and disappointment. I've seen people who are hungry to be unified around some basic common issues, and it's made me proud.

Statement of President Obama on the death of Vaclav Havel (18 December 2011) http://www.whitehouse.gov/the-press-office/2011/12/18/statement-president-obama-death-vaclav-havel

Context: Having encountered many setbacks, Havel lived with a spirit of hope, which he defined as “the ability to work for something because it is good, not just because it stands a chance to succeed.” His peaceful resistance shook the foundations of an empire, exposed the emptiness of a repressive ideology, and proved that moral leadership is more powerful than any weapon. He played a seminal role in the Velvet Revolution that won his people their freedom and inspired generations to reach for self-determination and dignity in all parts of the world.
