I would never do that but I do not understand the psychology of the new home/car buyer. 

I am an avid fan of Robert Kiyosaki and Grant Cardone and have more or less been going through their material religiously while maintaining a 50 hour+ week job and my own small operation of buying and selling on the side and going to school(psychology is a hobby subject though I have no interest in doing anything with the degree).

Business law Personal finance Business finance Accounting Micro, not so much macro economics Principles of Insurance Money and Banking Marketing (Conventional studies) English Composition Speech, Public Speaking Math Psychology Sociology These are all directly related to RE investing.

My UC Berkeley Psychology degree allowed me to bypass the 2-years of salesperson experience.

Real estate investing requires an understanding of Business Law, Finance, Psychology, etc. so any of those classes you're taking with your degree will be helpful. 

However, there is great benefit to becoming well rounded, an effective speaker, proficient writing skills, knowledge of history, politics, & psychology.

The psychology of a seller will change daily, which will drive the sale. 

He has the psychological part DOWN to a tee and knows the long game of buying properties and giving people what they need. 

I like to think of an example from the book "Influence: The Psychology of Persuasion" in which studies showed people were substantially more likely to let you cut them in line for a copying machine purely by using the word "because" in your request, even if the actual reason made no sense.

Business and Psychology.
