The entertainment industry can be tough. There are many cliche's, such as "It's all about who you know" or "It's all about right place right time." Neither of which are entirely untrue. However, I am a firm believer that anyone with some raw talent and a whole lot of drive can build themselves a career in post production sound - or any entertainment job for that matter.
If I'm making it sound easy, my apologies. It's absolutely a ton of work. Let me repeat that: getting a job in a highly specialized, creative industry where you are in competition with literally thousands of applicants will always be a ton of work. So why do it?
