In third (?) grade it was an assignment. Through the first semester, we were given 10x10 gridded paper and had to write numbers from 1 to 1000. More would get you stickers or something. I think I got to ~8000 by the end of the semester because I wound up around 13000 at the end of the year.
In whatever grade you're in when you're 12~ I took my olders sisters calculator (which she no longer needed), and typed : 0 => enter, and then res+1, that way whenever I clicked ' = ' it incremented by 1, effectively giving me a counter of how many times I hit the button. I reached 1000's per hour of class when I was just taking notes (no thinking to solve shit), and I kinda got into it, and kept at it for the whole year.
Doing stupid shit for a long time is fun.

I mean someone is very patient and dedicated to what they do
