Sometimes, as a writer, it’s difficult to think about large, overarching goals when you’re working on a project or planning to start on something new. Thinking, “I’m going to write a novel and have it completed by XX date,” is ambitious. And maybe it’s too much of a reach.
Instead, develop a plan. Write in chunks. Write sections of your novel or story that you find more interesting than others. Challenge yourself, but make your goals and expectations reasonable and attainable, because it will make the payoff satisfying.
