hey guys!
i did a screenplay last year... its really weird to think about again! (when you get to uni, you honestly DO forget that the HSC was such a huge defining moment in your life - i know, you've probably heard us uni students say it before and thought it was bullshit, but its surprisingly true!)
dont freak out about how much work you have or havent done... my screenplay didnt even begin to take any kind of shape until july... and dont worry bout conventions and everything like that yet - you can worry bout that later!
just keep writing lots of drafts... (i wrote 17 re-drafts of my major work) and try and approach it from fresh angles every now and then... i did a few completely unrelated scenes at 3am in the morning while wrapped in a doona, and hey, the ended up becoming integral parts of my storyline!
so just have fun with it, and allow yourself to be creative! best of luck eh!
