Honestly, working in the film business can be frightening. You aren't sure what you're going to be doing in the spring. You aren't sure if you're going to like the people that you're working with next month.
It's important to be able to find people who want to work as hard as you do, that want to advance their career like you do.
It's hard to know how to move from one level of the film making process to another. How do you go from being an Electrician, to a Best Boy, to a Gaffer, to DP, to Director, to Producer?
There's no formula. There's no format. A lot of times there is a very loose job description... and you just jump in.
