How did you choose your major?

I really liked math and physics, so I picked engineering. At Illinois, you can (or could at the time, I think it's changed) graduate as a "general engineer". In the later years, I discovered that I liked IE, and took most of my upper-level electives in IE. My internship before senior year confirmed that was a good decision.

Just take a wide variety of classes if possible. You will most likely find something you will fall in love with.
At least, that seems to have worked for me.
