I was constantly bored in elementary school and needed constant stimuli to be interested in learning anything. I cought on to most things immediately and it was easy so I never did any homework because why bother when it's just easy so felt like I was just lazy and also got called out on sloppy work because I just didn't bother spending time on it. All hand in assignments were always written the night before and always got a medium to high grade so why bother doing anything more? That severely bit me in the bum years later in university and fast forward another 10 years and I now have an ADHD diagnosis and in hindsight things are now finally making sense.
