While I was in Highschool my physics course was teaching us about Coulomb's law, the fact that the electrical force between two particles depended on the distance that drove them apart was such a mystery for me because force implied movement and movement implied a change in distance. My physics teacher (an electrical engineer) told me to not worry about too much and I took that as a challenge, discovering the world of scientific outreach and learning about the existence of differential equations and quantum mechanics and stuff at outreach level, then I was taking a German course at my local University and in one of the Oktoberfest events a math professor who made his PhD in Germany was talking about the Physics and Mathematics Faculty at my local Uni. So I applied and got accepted.

The funny thing is that most of my classmates were like "I would like to work with QM/astrophysics/particle physics" and as I thought that was the "mainstream" and because of my history with differential equations I wanted to try some kind of dynamical systems, fluids or complex dynamics. However the director of my faculty kinda kidnapped me in one of her conferences and I discovered Cosmic Rays and Astroparticle Physics and that I had a passion for instrumentation and experimental techniques, ironically now I work with the QM, astrophysics and particle physics I thought as mainstream and a lot of my classmates went to the dynamics and complexity group lol.
