When I went to university, I started out in Physics. I didn't really have a strong pull to study that topic, but my grades were reasonably good in that subject in highschool, and I had a general interest in the sciences.

One of my required courses early on was an intro to Computer Science. The course was taught using Python, and I just loved it - both the specific language, as well as the concepts covered. It was the only class that year that I actually looked forward to listening to the lecture, as well as to work on the assignments.

Over a decade later and now I program all day at work, and then work on my own code projects in the evening (extremely limited time permitting, I have a toddler and a newborn).
