In his book, Trump: The Art of the Deal, Trump discusses his undergraduate career:

"After I graduated from the New York Military Academy in 1964, I flirted briefly with the idea of attending film school...but in the end I decided real estate was a much better business. I began by attending Fordham University...but after two years, I decided that as long as I had to be in college, I might as well test myself against the best. I applied to the Wharton School at the University of Pennsylvania and I got in...I was also very glad to get finished. I immediately moved back home and went to work full time with my father."

I think Economics is the basis of Business.
I think Literature is the basis of storytelling using symbols and words, and thus, communicating.
I know I did the right thing.
