I used to be like that. When I was a kid, I only cared about games and anime (and I played games about anime and looked for anime about games). Back then I wasn't aware that other people weren't obsessed with everything, but looking back, I can tell that when I was like, 9, I annoyed the few kids I talked to because I was way more obsessed with specific games (and still am to this day) than they were about anything.

Anyway, my power level grew so big that it spread from one thing to another, and also, thinking way too much about specific things make me tend to think way too much about everything, and then I got into philosophy and philosophizing as well. Anime and games got me to use computers, and learn more about them over time, and eventually games got me into electronics in general, because of the hardware side of things, and influence from other people that are really into games. So, I got into technology in order to enhance hobbies that I already had, basically.

The internet in general made me more well-rounded, because I watched people that were interested in things that I liked, but they were also always into other things as well, and I absorbed their interests over time. My tastes also broadened a lot over time as I tried different things, so I like pretty much every genre at this point.

Relevant, I relate to 2:31 ~ 3:01 a lot:
