Not sure about what you’ve gotten yourself into with this MBA thing? You’re not alone. KJ Brooke is a veteran of the southern California hospitality business and is in her last year of an MBA program. People she talks to are often skeptical about her pursuit of an MBA, she says in an excellent essay for The Billfold, giving her looks “of bewilderment and awe, with a little bit of pity thrown in.”

But Brooke feels she’s made the right choice, which she defends with intelligence and wit in the article. Sure, she has little time for a social life, is buried with homework and puts up with resentment from her current co-workers; but when she’s done, she says, she’ll have a big bundle of new advantages, including increased self-confidence, comfort with numbers and  better earnings potential. And  if nothing else, she’s confident that she’ll never be caught flat-footed “by any ridiculous question thrown my way from a witty student or cocky boss.”
