Have you ever screwed up on the job?At one point in time you've probably heard it said that humans are prone to error, and that mistakes are a totally normal occurrence that help us learn and grow in life.

Maybe you send an email to the wrong person, or perhaps you forgot to set the timer on the TV to record your favorite show. Maybe you just left a tissue in your pocket before doing the wash.
