Investment books are a bit like golf instruction books.Michael Quinn said he always felt that there is a bit of truth in all of them, plus a bunch of personal adaptations which might not work for anyone else but the author.

The other day something prompted me to go back and look at an old investment book I had by George Soros

It was a follow on to the "real time experiment" he developed in the book Alchemy of Finance.  This one was humbly titled Soros on Soros, and is actually done in interview form, with Byron Wien as interviewer.
