I tried chemical engineering first because in my country's system we more or less have to pick what major we want to apply for since even before finishing high school, and I had to do this at thirteen. And then I got my very first computer as a high school graduation present. Quickly found out that enjoying the high school chemistry classes the most didn't translate to chemistry processes being what I wanted to do for the rest of my life. On the other hand, I fell in love with tinkering with the computer's software (first in windows, and then even more after I installed Linux) right away. I stuck it out with chemical engineering for a year and half, before finally dropping out and starting fresh with systems engineering (more or less my country's equivalent to computer science) during what would have been my fifth semester. Haven't looked back since and, much like the author says, I love solving those puzzles.
