Visors are great. First you look the part, and then you step into it.
It's been said that guys starting their first job on Wall St. might as well show up in clown costume because that would be a more accurate reflection of what they know.
But they don't. Smart guys look the part from day 1 so that the eventual transition into a sharp is seamless.
Similarly, when a guy walks into a sportsbook decked in his favorite team's gear, he might as well be wearing a Bozo outfit and be smelling like elephant dung. Square City.
You put on the visor. Wear a loose, comfortable shirt with pockets for easy access to pens and pads - and you keep your head down until you know your shite.
Follow the rules and maybe you'll become a player. If you don't want to do that just go outside and wait for the clown car to pick you up.
