I don't own any of them, but sometimes get them from the library for interview prep. Totally over the top for that, but sometimes inbetween googling and overcomplicated other books it's a nice relief to read through these lines, into which very obviously a lot of thought has gone. The opposite of all the fast-lived crap we have to deal with on a daily basis, and therefore also useful for the job. Motivating, I would say.
