Hello all~

I will be pursuing my fourth semester at Cornell University in the Arts & Sciences College this fall (undeclared yet), but I've been having doubts as to whether liberal arts is really for me. Over the past few months I contemplated if I should switch into Cornell's DEA Interior Design program, which is accredited and apparently one of the top B.A. programs of its kind in the US.
I've always felt that I'm more suited for the creative fields, and that making money and doing business really isn't the ideal future occupation for me. I realized, over the past year, that working in a job that fulfills my visions is what I want, and not a job that deals with inflating imaginary numbers (i.e. finance, business, etc.).
However, if I switch successfully into the Cornell Interior Design program, I will be delaying graduation by at least a year.
Would a more practical approach be finishing my B.A. degree for now, and applying for a masters program in Interior Design or Architecture (architecture in that architects can specialize in interior design whereas the reverse is not true - the flexibility of the degree) afterwards?
Any thoughts, suggestions, recommended post-Bachelor's programs, advice would be greatly appreciated!

Thank you all <3
