So I have finished the first draft of my novel, and I have the task self editing. I always have a bad habit of jumping between past and present tenses. I feel like the past tense stuff reads a bit easier. Let me give you an example: She slid the tray back through its purpose built slot, she heard the guard picking it up. VS She slides the tray back through its purpose built slot, she hears the guard picking it up. So basically I need to pick one and stick with it. But, which one? That is the question.
