If there is any one secret of effectiveness, it is concentration. Effective executives do first things first and they do one thing at a time.
Peter DruckerEvery first-rate editor I have ever heard of reads, edits and rewrites every word that goes into his publication.... Good editors are not 'permissive'; they do not let their colleagues do 'their thing'; they make sure that everybody does the 'paper's thing.' A good, let alone a great editor is an obsessive autocrat with a whim of iron, who rewrites and rewrites, cuts and slashes, until every piece is exactly the way he thinks it should have been done.
Peter DruckerIf something fails despite being carefully planned, carefully designed, and conscientiously executed, that failure often bespeaks underlying change and, with it, opportunity.
