"Creative people have very different abilities than cognitive thinkers. If you force an advertising copywriter to labor over a time sheet every day, their creative work may suffer. Time sheets are actually counterproductive to the creative process – they force a creative thinker to ‘switch gears’ again and again throughout the day. In fact, they can actually intrude on what the copywriter or graphic artist is really there to do in the first place."

— Dr Sandy Calkin (workplace psychologist)
