Query: Thought-Provoking

I thought this was going to be a book about how to increase concentration and performance on complex tasks, but it turned out to be more about assessing yourself and your circumstances and becoming better adjusted - the pursuit of happiness. Writing style has changed so much recently that the book feels like it was written in 1970 not 1990, but you have to try to ignore that and connect with the author's empathy to get the most out of it.
