A blank page isn’t good. Writer’s Block. A failure in creativity.
A blank canvas is good. Prepped for those first sketch lines, that first application of paint. Then you layer until the image takes on form and is revealed.
Writing works in a similar way.
The blank page is waiting for those first words. That first layer onto which you will add or take away to reveal the completed image.
How much you add or take away is probably dependent upon your style.
The first rule of being creative is that you create – you have a blank then you add something to it.
So take that blank page, or screen, and throw some words at it.
