Often enjoy these lines and I find myself including. "Third group: Those who never surrender. This group, maybe 2 or 3 percent of the total, doesn't let pessimism dictate, doesn't believe in surrendering to suppressive forces, doesn't believe in crawling. Instead, these people live and breathe success. This group is the happiest because it accomplishes the most. These people become top salesmen, top executives, top leaders in their respective fields. These people find life stimulating, rewarding, worthwhile. These people look forward to each new day, each new encounter with other 'people, as adventures to be lived fully."
