Query: NO SUBSTANCE, NO FACTS, JUST FLUFF

I bought several medical career books and this one was by the worst. I have no clue how this book got such high ratings. It wasn't useful at all. Sure it's cheap but I wouldn't buy it if it was $1. That's how bad it is.DETAILS: It has no substance or factual information, it is not researched at all, it replies on author opinion without any facts, feels like the author is just trying to "fill pages," and just repeats common sense stuff over and over again like be sure to research your career choice or know yourself.In other words, it doesn't tell you anything new or anything about medicine and IT DOESN'T GIVE ANY FACTUAL INFORMATION, just common sense stuff and fluff to fill pages.I bought several books and I highly recommend the Princeton's Reviews "Planning a Life in Medicine." Just buy that one. That's all you need. Skip this book!
