When I first looked at the question, my reaction was "Well, I don't - not really", but then I thought about it some more. At some point, I realized that without math, I would cease to function. You see, math is not about sitting around in classrooms and listening to infinite lectures. It is about applying numbers in a useful way. I derive enjoyment out of almost every CS class I take. And math is integrated into every one of those classes. It isn't always so obvious as a matrix inversion. Sometimes it is the addition of a reference to some numbers. Other times it is figuring out a set of principles. It really is the smallest things that make the difference. You may claim that this is an imaginary claim, but I know it to be real.
With all probability, I would be completely lost without math. Do you need some proof? Try traversing campus without planes or points. Then you will realize what a ray of sunshine math really is. It isn't just a segment of our lives, or a theory that runs tangent to what we do, but the base of everything. There is no way to divide our lives into a math portion and a non-math portion. It is just a constant part of what we do, even if the magnitude of how it intrudes is variable. Life without math just wouldn't be normal.
So why do I math? Because it is as natural as a log. Reality is just a vector for applying numbers, patterns, sets, and all things math. And you know what? If you groaned at a single pun in this essay (or even recognized a fraction of them), you math too.
