My daughter is learning how to drive, and it's been an interesting lesson on what the world looks like to a perfectionist. She has pretty much been a perfectionist since birth, missing recess in kindergarten to make sure her coloring was perfectly inside the lines, and drawing eyelashes and fingernails on her pictures when the other kids drew stick figures. Now, she is driving, and it takes 10 minutes to get the seat, mirrors, steering column, etc., in just the right spots. She has never driven over the speed limit, and most of the time is well-under because going over isn’t the right way to do it. She has to make sure the radio is turned off, everyone’s devices are turned off or silenced, and all distractions in the car are eliminated. And of course, as my driving is far from perfect, I hear lots of advice on how I should be doing things. It's been an interesting adventure, but has also given me a lot of insight into the mind of a perfectionist.
Most sales managers also have one or two people on their team that fall into this "perfectionist" category.
