Sources of advice
I read a terrible book a couple of years ago: The Brazen Careerist by Penelope Trunk. It was full of trite advice that didn't actually mean anything, the practice of which would only turn you into a self-obsessed and bitter person. I thought I'd find other people felt the same way about it, but it seems it has rather good ratings on Amazon.
Today, I came across a person who has succinctly described all the things I loathed about this book, and on further investigation, the person behind it:
We should take advice from people who have their own life together. We should read writers who write because they have something to say, not because they are desperately craving validation and will do or say anything to get it. As I slowly realized how badly she fails in both those areas, I went from anger to a sad, deep pity.
