When a reader finishes what you wrote, you'll want them to walk away with your core message. That means your writing needs to be concise and clear to whoever chooses to read your work. However, how do you ensure that what you put down on the page makes sense to others? Well, the answer is easier than you might think: critical thinking. Now you've probably heard ever since middle school that critical thinking is important, but it truly is the heart of creating thought-provoking writing. Critical thinking allows you to reason and correlate thoughts together, whether you're writing a persuasive essay, fantasy novel, or blog post.
