Do you know how I got into FOSS stuff? Embarrassingly enough I went to a summer camp between junior and senior year of high school, I was def the oldest one at the camp, and took an "Intro to Linux" class
I got so excited I went home and bought a Red Hat for Dummies book and installed it from the CD-ROM
I got so into FOSS'y stuff over the next year my parents tried to do an intervention before I left for college
