Some people get real addicted to the string of letters that follow their name. These are each called a Name Suffix. You can be utterly booksmart and never accomplish squat. Professional suffixes be damned.
A guy with whom I once worked and I used to joke about this, and we came up with our own desgination: GSD. It stood for "Gets Shit Done." All the pretense in the world can't save you from an inability to make it happen. Ultimately, that's all that counts.
