Very underrated book, it depicts psychology of a person who doesn't understand why markets go up and just gets lucky. One must appreciate honesty of the author, because most people would never write about their of fatal failures. This book is easy read, but emotional rollercoaster. If you ever been in a similar psychological pit whole you would understand.

I found this book on Project Gutenberg for free, and read only because I knew the author was good. But the book surprised me, it resembles what Artificial Intelligence might do to humanity (it's not even about artificial intelligence), it's very short and probably worth a read, something in between horror and science fiction, with perfect story telling. Left me for hours little bit disturbed.
