I read this summary when first posted, and got nothing at all from it.
I then read the original, got inspired and motivated, came back and read this summary, and found it concise and useful.
I often find reading (even good) summaries feels similar to studying with someone else's notes for a class I didn't attend.
I can think of no better way to spend my karma than on encouraging people to read this 19th century self-help book. It's free and online in full.
The guidelines on what makes an appropriate front-page article be damned, or, if necessary, enforced by official censorship.
Thanks to User:sfb for the quote that led me here, although the decision to post is entirely my own.
