We meet fear and worry every day. But when fear and worry cause us to lose our head, things get really bad. During the 1930's we were in deep trouble as a country. One out of three people was out of work. F. D. R. said, "The only thing we have to fear is fear itself." He knew that if Americans looked at their troubles with a clear head, they would work out of them.
Did you ever hear the story of Kelly？ One day, Kelly walked over to her neighbor Casey to borrow his wheelbarrow. On the way Kelly started to think, "What if Casey isn't home？" A few steps further the thought hit Kelly. "What if his wheelbarrow is broken？" Kelly was getting more and more upset by "What if". Kelly began to say to herself, "What if Casey won't lend me the wheelbarrow？"
By the time she rang Casey's bell Kelly was in an angry mood. Casey came to the door and greeted Kelly in a friendly way. Kelly pulled back and let Casey have one on the jaw, "Keep your dam wheelbarrow," growled Kelly as she walked back to her house.
