How to Sharpen Your Thinking

If you collect personal success books, this would make an interesting addition to the collection.  It's not particularly in-depth and the very back cover has a bit of a water stain (no big deal really), it has some foxing, and there is a tiny bit missing from the back cover.  The pages are bright and easy to read.  The only reason it is in the bargain bin is because it's really only worth a few dollars, truly I'm not sure who would want it.  Success enthusiasts I suppose.  Anyway, $2.49 and it is yours.
