I was talking to a friend and he told me I should read a book. It is a classic business book written about the same time as How To Win Friends And Influence People by Dale Carnegie. I can not remember the name of the book. Any suggestions on classic business books that are timeless written in the 1930's or so?
For some reason the book "Think and Grow Rich" by Napoleon Hill came to mind (I just looked it up and it was written in 1937) although I don't endorse its content ...
