"Nothing quite like a blank page to get that fresh creativity feeling"
Do your work a favour and "start over". It can be one of the hardest things to do. Especially if you've already put a lot of time and thought into the process so far. Starting again can feel like loosing all the work you've done so far!
Instead trust that the work is in you, its still there. And by starting again, re-writing, re-drawing or re-shooting you are only adding to quality of your work.
After all, YOU were the one who did it in the first place...you can do it again!
