Many of us were taught that no sentence should begin with "but." If that's what you learned, unlearn it - there's no stronger word at the start. It announces a total contrast with what has gone before, and the reader is thereby primed for the change.
William ZinsserUltimately the product that any writer has to sell is not the subject being written about, but who he or she is.
William ZinsserFinding a voice that your readers will enjoy is largely a matter of taste. Saying that isn't much help-taste is a quality so intangible that it can't even be defined. But we know it when we meet it.
William ZinsserDonโt say you were a bit confused and sort of tired and a little depressed and somewhat annoyed. Be tired. Be confused. Be depressed. Be annoyed. Donโt hedge your prose with little timidities. Good writing is lean and confident.
William ZinsserThere'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.
