After 6 years in the Navy, I enrolled in college as a Social Work major, found that I enjoyed research, and switched to Sociology, then decided to switch again to History as a major, with Psychology as a minor, and by the end of my 6 years in college I opted to also go for a Secondary Education license (High School teaching credential program).
After all that, I ended up in the computer industry straight out of college and never formally used my college education (I learned computers in the Navy and on my own, plus I worked for NCR Computer Research while in college).
Academically, I would say that the Humanities program I was in was excellent (Art History, Anthropology, Philosophy, Linguistics, etc.), and I use what I learned in Statistics classes (not a part of my major/minor) almost every day of my life.
