This may sound silly at first, but it's just a little shift in perception that could make all the difference to your work, make you a better writer, and shave years off your time spent breaking into the biz.
If you've been writing fairly consistently for several years, reading scripts and blogs and how-to books, learning dramaturgy and honing your craft, then it's probably safe to say that you're a far more knowledgeable and experienced writer than when you started out.
Wow what would that younger self give to have the knowledge of wordsmithing and the industry that you have now? What if there was some way you could time travel and brush up those early scripts?
Well there is. Just dig them out of the drawer.
There's presumably something in the concept that drew you to those themes, to that subject matter.
Maybe it's worth having a fresh look from the POV of the older, wiser, more experienced (more jaded) person you've become. It might seem like an extremely time-consuming endeavour, but in comparison to the several extremely expensive days a script consultant might spend poring over your story and word-choices, maybe it doesn't seem such an outrageous endeavour after all.
Wait, but why is a script consultant telling you this? Because making money isn't my primary goal. I'm far more interested in simply helping my clients and readers get to where you want to go.
When I achieve that I'm happy, you're happy, and my marketing becomes word-of-mouth, which is much better, way cheaper, and far less time-consuming.
