Honestly, I think I was born vegan and forced to be carnist.
Even though it sounds cliche, I never really liked meat. I was always picky about meat/fish and if it resembled a corpse, I wouldn't eat it. I think I first cut out pig meat, then all meat. And that all whilst being 9 lol. I didn't really think about animal products at the time, mostly because I was brainwashed by the industry and thought they treated their animals well. But as time passed, I found plant based milk way better anyways and kinda transitioned into being vegan. At that time I was 12 I think. And now, I can't imagine living any other way.
