One thing authors should avoid is being vague or inconsistent about their goals and expectations. Early in my experience working with literary agents, I noticed that when authors weren't clear about their vision or deadlines, it caused unnecessary back-and-forth and slowed progress. To foster a strong relationship, I encourage authors to be transparent and communicative from the start. Sharing honest updates, even if there are setbacks, helps build trust. Also, respecting the agent's expertise while being open to feedback creates a collaborative dynamic. I've found that clear, timely communication combined with mutual respect makes the partnership smoother and more productive for both sides.
