We're all familiar with the term "muscle memory." Once you've learned to do something--serve a tennis ball, play a difficult piece of piano music, or draw a lifelike human hand--your body seems to intuitively "know" how to reproduce that action. But researchers at Johns Hopkins university have recently discovered that our ability to perform a physical athletic or creative task isn't entirely about what the body has learned to do right. Instead, we owe our success to the hundred times we've tried to master a skill and failed.
