I thought my editing was finished until I printed out a hard copy. Hmmm! Essential part of the editing process for me now.
Put it aside
I know, it’s hard! But it is crucial. Having immersed myself in my novel for months and months, I became too close to it. I could no longer review my novel with any degree of perspective. By forcing myself to have a break while I worked on something else, this time was not wasted.
