From Donald Trump: The Pursuit of Success, pg 13 – one who constantly seeks out new ways to make claims upon attention and diligently measures and assesses the success of these innovations:

For decades, no one has made a more insistent claim on the nation’s attention than this man. Trump begins each day with a sheaf of papers detailing where and how often his name has been mentioned in the global press. The reports are typically too numerous for him to actually read, but the weight of the pages gives his sensitive ego a measure of his importance on any given day. This need to be noticed, and his drive to satisfy it, has made him a singular figure worthy of close inspection.
