Will being a brilliant software engineer get you a smokin’-hot babe for a wife? No, it won’t. (There are exceptions to this.) But unless you’re a complete jerk, there’s probably an accountant with a cute smile who shares your love of HP Lovecraft, or a genetics lab tech with a great laugh who plays Dungeons and Dragons, or an IT consultant who loves to cuddle and is willing to put up with your cat’s YouTube fame.
It is less the case that shy, successful people are purchasing access to a mate and more the case that the shy, successful people have finally found a common breeding ground to spawn.
