I almost always urge people to write in the first person. ... Writing is an act of ego and you might as well admit it.
William ZinsserMany 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 ZinsserWriting is linear and sequential; Sentence B must follow Sentence A, and Sentence C must follow Sentence B, and eventually you get to Sentence Z. The hard part of writing isn't the writing; it's the thinking. You can solve most of your writing problems if you stop after every sentence and ask: What does the reader need to know next?
William ZinsserBe wary of security as a goal. It may often look like life's best prize. Usually it's not.
