I recently read the book “A man for all markets” (https://www.goodreads.com/book/show/25733505-a-man-for-all-markets) by Edward Thorp, who is a mathematics professor and then proved wrong the conventional theory that it is impossible to beat the casino. After that, he went on to become a very successful investor and trader in the stock market. You can read more about him here – https://en.wikipedia.org/wiki/Edward_O._Thorp
The book is a gold mine of wisdom that one can learn and apply to become a better person, parent and investor. Click here to read the rest.
