Mitt always had a strong laugh and at the time of the proposed laughing ban, he was the top leader in the mission, assistant to the mission president. So he really dispelled the anti-laughing crowd, mostly with his humor.
In the middle of his service in France, he was the driver in an automobile accident in which a woman who was very dear to us was killed. He could have been much more morose, but he led us through that difficult time and returned to his cheery self.
While we were there, we read the book "Think and Grow Rich!" by Napoleon Hill. Some of our church leaders recommended that we use those concepts of positive thinking to overcome doubt and discouragement so we could perform at a higher level. They meant it as applied to our missionary work, but of course it could be applied to business as well. I've often said that Mitt and I read that book at the same time but he read it better than I did.
