My college years are a blur.
In cop shows, the police don't get to rag on each other and rag on their commander and rag on the person they just pulled over. That was all 'Reno' was, and I think that's all cops do 90 percent of their day.
The good thing about being a writer is that you don't need anything except for a laptop. You can really do your own work, and if you're not manically compelled to write all the time before you do it professionally, it's probably not a business for you, anyway.
I would say, A, you can't really teach anyone how to write good characters, because it's something you have to teach yourself or already have innately in you as a storyteller, and, B, coming up with a good screenplay is a very, very small fraction of what it takes to be a good screenwriter.
