Failure has seldom been sexier, with advocates believing that if you're not failing regularly, you're not pushing the boundaries far enough. Such cheerleaders often evoke the spirit of Edison, who famously remarked that his thousands of failed experiments were a necessary precursor to the invention of the lightbulb.
Edison's notorious example merely serves to illustrate the importance of learning from each dead end so that you can be more successful next time. To take such constructive feedback from failure, it's vital that we understand the essence of what our failures represent.
