Good read needed while on vacation

[Kellie Powell]

My husband and I are going on vacation in a few weeks.  We will have a lot of down time.  I enjoy a good book that will help me on my way to success.  Knowledge is power! What are your favorites?  I know BP has book recommendations, but I want to know which books hit home for you!  I've read Rich Dad Poor Dad, Real Estate by the Numbers and Rental Property Investing (by Brandon Turner).    We mainly flip houses together but I also have a W9 job.  I'm also interested in investing funds / retiring early.   Help a girl out here.  What was your favorite???
