You never step in the same river of thought twice, because neither you nor it are the same.
Jacques BarzunTake a portion of wit, And fashion it fit, Like a needle, with point and with eye: A point that can wound, An eye to look round, And at folly or vice let it fly
Jacques BarzunOne great aim of revision is to cut out. In the exuberance of composition it is natural to throw in - as one does in speaking - a number of small words that add nothing to meaning but keep up the flow and rhythm of thought. In writing, not only does this surplusage not add to meaning, it subtracts from it. Read and revise, reread and revise, keeping reading and revising until your text seems adequate to your thought.
