When writing a biography, start by researching the subject’s life extensively, gathering facts, anecdotes, and personal insights. Create a timeline to organize significant events and milestones. Focus on developing a strong narrative by highlighting key achievements, challenges, and turning points. Use interviews and reliable sources to ensure authenticity. Organize your content into a clear structure with an introduction, main body, and conclusion. Maintain an engaging and authentic voice, bringing the subject to life. Lastly, edit and refine the text for clarity and coherence, ensuring the biography flows smoothly.
