Is day trading a viable career if I am skilled enough? And what college classes would that translate to?

Before everybody starts telling me how risky it is and how most people fail - I already know. For my first question I am just wondering from a logistics standpoint like insurance or anything else if they care that my income would not be too steady.

I am spending plenty of time practicing and learning.

One of my biggest questions is what should study in college? Should I focus on more accounting and business? Or more computer science related classes? Should I major in one, and minor in another? I want to be able to day trade for myself once I am out of college (the way things are looking may get full scholarship and be able to graduate without debt) with my own money as mostly my main source of income. However I want to still have plenty of job options, and if things are not working out or I need steadier income for a little while I want to still be a strong applicant for a finance related job. I also do want those classes to help me get a better understanding of economy, stock market, psychology, some light programming maybe for automating some things, etc.

Any recommendations, advice, or mentioning other things to consider would be appreciated!
