Continuing my Investing Education, What should I read next?

[Brian Oberg]

Looking for my next book to read.  In the last 2 months since we joined bigger pockets, I have read the following:

How to Invest in Real Estate by Brandon Turner (Great Book)

BRRRR by David Greene (Another Great Book)

The Book on Tax Strategies by Amanda Han (Highly Recommend)

The Book on Advanced Tax Strategies by Amanda Han (Great Book)

Your Best Business Entity for Real Estate Investing by Michael Landtrip (Horrible Book, don't waste your time or money)

Fortunately I have two international flights coming in the next couple of weeks with plenty of time on an airplane to read, so I want to make the most of my time.  What do you suggest and why?

Thanks,
