According to the author, what is the relationship between media violence and real-life violence?

[(63) In your quest for success, enthusiasm means that you believe deeply in what the company is doing. ]You also believe that your job is important and contributes to the cause. It means that you’re willing to work your butt off (努力做事) to achieve the company’s goals. [(64) Real enthusiasm is when you leap out of bed in the morning and attack your day full of energy. ][(65) You have zeal for the work you do and the people you work with. This pushes you to improve and become a better person. ]Enthusiasm means that you are stimulated by your work，and are able to find new challenges and keep growing professionally.[ (66)Furthermore, most jobs have some elements that are less fun and more difficult to carry out. ]This is where passion really comes into play. [(67) When you love what you do, it isn’t too difficult to get mentally prepared and get the job done. ]The hard part is performing equally well in those less interesting tasks.
