A degree (or similar) on its own will not lead to a career in performing arts. You cannot expect to walk out of college or university and move straight into your dream job.
Getting involved in university theatre and music events should help. The example jobs listed here all require plenty of industry experience too. There is no room for diva behaviour when you are getting established. You will need to work hard and be nice to the people you work with. A bad reputation can be hard to shake off.
