There is a HealthygamerGG video where he talks about gifted kids as special needs kids bc of this factor. I found it really enlightening. I definitely had to confront it in my own life.
Same thing happened with me. By the time I was halfway through high school, everything was so boring I couldn't focus enough to actually do any work. Most days I would just skip class and I rarely did any homework at all.
The principal told by parents "we have nothing else to offer your child", so I dropped out and started working fulltime. As much as I know I should be advocating to stay in school, I don't regret it for one second. As soon as I turned 18 I already had enough money to move out on my own and never looked back. Never went back to school.
As far as work qualifications goes... writing software, I have always gotten work based on my experience alone, nobody that I actually wanted to work for ever cared about some piece of paper, only what I could do.
There is also one where he talks about how about half of his suicidal patients are not delusional and don't have some mood disorder, but are correctly recognising that their lives objectively aren't worth living.
