Next, focus on your audience. Who are you writing for? What style is likely to engage them? If your audience is a group of academics, your writing style might need to be formal and structured. If you are writing for a younger audience, a more conversational and informal style might be more effective.
However, don't let your audience dictate your writing style completely. Your style should also reflect your personality and values. If humor comes naturally to you, let it shine through your writing. If you're passionate about a subject, let your enthusiasm permeate your words.
