Republican presidential candidate Mitt Romney appeared on MSNBC's Morning Joe on Tuesday, where co-host Joe Scarborough asked him about his experience as a Mormon missionary in France in the 1960s. "Talk about your rejections as a missionary knocking on door, after door, after door in a hostile environment," Scarborough asked.

Romney recalled five months he spent in one French city, where he said near-constant brush-offs built his resilience:

"We knocked on doors from morning until quite late in the evening," he said. "We didn't convert one person in five months. So, you understand the rejection, you know that's a pretty high level of rejection and you get used to it. You say, 'okay, what do I believe, what's important to me,' and you don't measure yourself and your success by how other people react, but instead by how you're doing and how you feel about the things you care about."
