It did for me. The trouble with being an art major is that while you can BS an essay, if you spend less time on an artwork it is immediately obvious. You really do have to put in the work. But I was also undisciplined - it took the whole first semester to break my habit of starting my homework at 4 am!
The main thing I spent my time on in college though was D&D. As it turns out, though, D&D and DMing turned out to be far more relevant to what I do for a career than anything else I did in college!
