I can't understand why "694 people found this helpful". It's not a very good review or even a review at all. The only review-like part of it is "I still don't feel I have learned everything the book has to teach." which is very cryptic. Why doesn't Paul Graham feel like he has learned everything from the book? Is it because the book has a huge amount to teach and it isn't possible to consume it all in a short period…
I have the feeling anything PG says these days is applauded w/o proper reflection. Maybe it’s just me, but I have the feeling most of his thoughts are quite profane
1. relating or devoted to that which is not sacred or biblical; secular rather than religious.
2. (of a person or their behavior) not respectful of orthodox religious practice; irreverent.
3. treat (something sacred) with irreverence or disrespect.
That all said, I wouldn't go as far as to say profound. Just insightful commentary distilled from experience.
