There are two types of email addresses you need to have if you plan on acting. You need a personal one and a professional one.
Have you ever worried about sending your resume to potential employers because your email address says email@example.com? That's why you should get a second email.
Don't give the professional email address out to your friends, only to professionals. The reason is so that you don't ever get the two mixed up.
Gmail is free, so there is no reason you can't make your second email address right now, as soon as you finish reading this.
Remember that there is no time like now. Change your email, make it professional, and start getting jobs.
Oh, one other thing: professional doesn't mean something ridiculous either. You don't want to have an email that says firstname.lastname@example.org. That's just ridiculous!
