I probably have 100 in my library...
Reminisences of a stock operater,
Edwards and mg gee,
and the market wizards books stand out
zen and the art of markets- tiny book
outside of trading,
Beat the dealer (about blackjack) and Zen and the art of motorcycle maintainance
The psychology books, trading for a living, the disciplined trader, etc, etc are good.....but how to apply all that is the issue.
My best lessons are observing markets, making and Especially giving money back (not to be confused with losing), writing my own book (journal), periodic self analysis and the few great mentors I was lucky to crossed paths with.
