I did this. I realized what the GP said when I was 13. I was either bored working on subjects I liked because I knew them or bored working on subjects I didn't like and had no interest in. I was an angsty teenager who could not handle this, so I dropped out. At 18 I got my GED, after doing no studying, and that got me into a local college. After my first year I transferred to a less than Ivy League college in my state. I had no support, and therefore did not use this opportunity to do great things, but I still ended up pretty much where I would have had I not dropped out. I look back on that time as my pre-working early retirement that allowed me to figure out what was important to me.
