Dave and Brandon discuss some of the concepts in the book "Top 10 Distinctions Between Millionaires & Middle Class".  Some of these points can be controversial! 
From the book....
• Millionaires think long-term. The middle class thinks short-term. Create a clear vision of the life you desire, and focus on it.
• Millionaires talk about ideas. The middle class talks about things and other people. Ask some positive “what if” questions every day, and bounce ideas off successful people who will be honest with you.
• Millionaires work for profits. The middle class works for wages. Take calculated risks and learn to take advantage of good opportunities.
