Like Napoleon, the prototype for what one thinks of when imagining a psychologically damaged person imprisoned by the implications of his shortness, stout bosses have this tendency to be bastards who are always trying to prove something. Although short people are far likelier to rise to power because of their complex, they are equally as likely to fear managing tall people.
Hence, anytime your superior tries to prove he has authority over you, it is key to tower over him with your imposing height, reminding him that you could crush him at any time you wish. You’ll not only have the advantage of reminding him of his true stature, but you’ll also get it into his head that he never wants to be near you so that no one can acknowledge how short he is–which means the demands of you will be fewer.
