Holy Crap. Some guy at Forbes wrote an article called, "If I Were A Poor Black Kid." Why a poor, black kid? Why didn't he just say, "If I were a kid"? If you remove "poor black" from his essay, it still makes grammatical sense AND it doesn't sound like some WHITE guy just got total amnesia about our history. So if you read the article, just try to ignore that it's completely misplaced advice, but try to focus on the details. Otherwise, damn, he sounds stupid.
With that in mind, I'm going to attempt to solve all the problems of the out-of-work librarian. And it will probably sound just as stupid.
IF I WERE A POOR OUT-OF-WORK LIBRARIAN.
If you're a librarian and unemployed, I don't need to tell you that there are lots of other librarians out there looking for a job.
If I were a poor, out-of-work librarian, I would read "If I Were A Poor Black Kid." And I would do what the author says to do about "getting technical." Most of this stuff can be learned through your local library. I hope you knew that.
If possible, I would learn another language. As much as I could. I would give up my free time and devote every second to making myself the most attractive candidate for the job. But for now, I'll assume you've made it past the application stage and have been called for an interview.
