Quote from nutmeg:
Non-Trading books that every trader should read
-----------------------
"The Gift of Fear". (basically, discover intuition and why we should embrace intuition).
"Blink" Although there is one short chapter which mentions trading the book is about gut instinct.
While we all would like to live and die on gut instinct or intuition, it is real and has a basis in knowledge and experience. Pretty cool subject and a refreshing read from the ordinary finance genre.
