It always shocks me how naive about the business side of the profession new and recently graduated actors are.
All of the acting training, tips and techniques that you learn at drama school will be powerful and useful once you are in the rehearsal room. To get yourself into that rehearsal room you need to book the job and booking the job takes more than training, technique and tips. You need to start behaving like you are a business, behave like a professional.
