It is amazing how one finds the strength to get up when one falls. An engine girl once told me "nothing motivates like spite" (that tenacity to refute certain believe system)...When she was in 300 level and was scared of failing a course, she went to seek advice from someone who  had experience and overcame what she was  about to go through. With a sad expression she said"the person she looked up to told her that it's impossible for her to pass that course because many failed (her included)

Well news flash “I am autonomic in nature because I don't like being told what to do” she said  so yeah ... The thought of failure can  make one  more resilient, strong and diligent but the fear of failure paralysis  ones  thoughts and actions.
By overcoming, she became an icon of hope to younger generation making them believe that success is possible.… Her  stubborn determination to debunk beliefs of failure is what fuels her motivation.
