I'm very new to screenwriting but I can agree that prep is key. In my limited (2 months) of learning the craft, my true allies have been my whiteboard and cork board/3x5" cards (along with books I've picked up). I've spent many a night coming up with my outline and filling out my beat sheet. While not as fun as writing, I know it will make my writing more fluid and personal.
I can't wait to start writing but I didn't want to stumble half way through and give up. I feel confident now that my story is in my place and it is up to me to make it come to life.
