Advice needed for prospective entrepreneur

I would be starting with college in a short while. I am interested in the entrepreneurial side of business rather than the technical side and after doing a lot of research I chose philosophy honours with a minor in math( actually it's different than a minor as it is intensive itself and can enable me to pursue a math masters.) I chose philosophy partly out of genuine love for some of it's themes but my main reason for choosing it was that the skills that it provides are invaluable in the business world. Anyways after my graduation I plan on enrolling in programmes like Cambridge's 1 year diploma for non-eco graduates which compresses a 3 yr degree into 1 tear and can also be used to pursue a masters in economics.
I would like to know your opinions about the viablity of my plan and the challenges hat i would have to face
