There's no subject you don't have permission to write about. Students often avoid subjects close to their heart ... because they assume that their teachers will regard those topics as 'stupid.' No area of life is stupid to someone who takes it seriously. If you follow your affections you will write well and will engage your readers.
William ZinsserNobody ever stopped reading E. B. White or V. S. Pritchett because the writing was too good.
William ZinsserThere are all kinds of writers and all kinds of methods, and any method that helps you to say what you want to say is the right method for you.
