Yes. I mean, I think the guy is an arrogant, unethical bastard, but IF you can just get past that and keep an open mind I think he does have a few interesting points on productivity, priorities, questioning what you really want, etc. There's actually a lot of stuff in the book that I agree with, but there's a lot that really irks me, too.
I don't know enough to comment one way or the other about the guy, but it seems a bit harsh to call him arrogant and unethical without at least describing how/why.
