Sam writes: How do you go about finding a mentor and asking someone to help you through multiple drafts/multiple projects?
Ask any successful writers how they got to where they are, and the answer usually involves someone who took the time to offer guidance and support. It could be a producer, director, executive, or another writer - but mentors are constantly helping new writers improve their work and navigate the industry. I've been lucky enough to find a mentor who has taken an interest in my writing in this way.
Lots of people will help you on your path to becoming a professional writer, whether it's forwarding your resume on for a job or giving you notes on your script. But the thing is, not everyone wants to be a mentor. Some people really enjoy helping young writers develop their talent - and some don't. You can't force it to happen. Also, professional writers can be really busy. Don't take it as a personal slight if someone isn't able to help you.
In my experience, a mentor/mentee relationship is most likely develop if the A) the person really does want to be a mentor, B) s/he thinks you are a talented writer with a lot of potential, C) you both share the same taste, and D) you've bonded on a personal level. You might meet the friendliest writer in the world, but if she writes romantic comedies, she's probably not the right person to guide you through four drafts of a horror movie. In a recent draft of my script, my mentor wrote down a joke pitch before flipping the page and seeing that I had written the exact same joke already. We obviously have similar brains.
I'm not sure it's really possible to actively seek out a mentor - and I think it would be awkward to ask a writer to be one. You just have to keep meeting people and see if anything clicks (in my case, it happened organically). Also, Sam's question about multiple drafts and projects might be a lofty idea. I would aim for finding someone to offer to read just one draft of one script - and then see what develops. Maybe you'll get some great notes. Maybe you'll get passed onto an agent or manager. Maybe you'll get a mentor. Any of those things would be helpful.
