A musician. And I guess I succeeded, even if I don't make livable income off it...

According to a fill-in-the-blanks Dr. Seuss book I have from when I was a kid, I wanted to be a cop (I completely forgot about that). Cop would definitely be the last job I'd want now. Even if I were capable of being a cop, which I'm not, I hate cops, I think they're bullies, and there are some good ones, but even if I were a good one I'd have to swallow my conscience and abide by the Blue Code. Later on, like in junior high, I wanted to be a "mad scientist."

I wanted to become a professional interpreter at some point.

I wanted to be a doctor

astronaut

An astronaut or a TV show presenter or Jérémie from Code Lyoko. That cartoon is what got me to meet my best friend, learn programming, and move 600km to live near him.

pilot

I wanted to be rich, I didn't really care how I got there

A construction worker. I don't really remember the reason, but I was really into Lego, so maybe being involved in building something big sounded like a great idea to me.

i can't really remember, probably an astronaut or astronomer, space is really really really cool

I, like many other kids, wanted to be a youtuber. I now realize that being famous as a trans person or furry would be a remarkably bad idea, also being famous kinda scares me in a way I can't describe.

don't remember, other than that it changed a lot. astronaut, probably.

I want to be a restauranteur

an astronomer. i had a huge hyperfixation on space (and still do.)
