To name a few, though not necessarily RE books:The Millionaire Next Door - StanleyRich Dad Poor Dad - KiyosakiThe Automatic Millionaire - BachThink and Grow Rich - HillSet For Life - TrenchPS: All should be read early in life and re-read annually since the steps, tasks and habits described need time to take hold. 

@Wayne Brooks Annual insurance expense provided was $670, but all will be verified to be sure the numbers aren't misleading during the 17 day contingency period.

@Scott Wolf thanks for your input Mr.
