To me, having 'material' for an essay means not only having something to write about but also having something interesting and original to say about whatever that might be.
This quote emphasizes the importance of depth and originality in writing. It suggests that merely finding a topic isn't enough; the true challenge lies in cultivating a unique perspective and meaningful insights. Engaging with material thoughtfully transforms a basic subject into compelling and memorable content. For writers and students alike, this highlights the value of critical thinking and creativity in producing work that resonates beyond the surface.
