[Josh Justiniano]

What are the best business/economics books you've ever read? 

Here are some I'd like to share with you that I have found very informative! If you have any, particularly audio please post. I'd like to hear about them.

Here's a few that top my charts:

Real Estate Finance: Risks and Opportunities by Peter Linnerman 

Principles of Real Estate Syndication by Samuel Freshman

Investment Analysis For Real Estate Decisions by Gaylon Greer and Philip Kolbe (bought that one for .01 cent on Amazon. Extremely valuable info still applicable today)

Audio:

Basic Economics by Thomas Sowell 

Good To Great by Jim Collins 

E-Myth Revisited

[Alex Gerasimov]

I love Brian Tracy..  All of his stuff is good.
