I just took the quiz you posted to @begtodiffer, and as I suspected, I'm INTP
I can't do schedules for the life of me. I'll often get lost researching or doing work for hours on end, and completely forget about everything else. I'm pretty bad with time in general, so I've switched over to a life where I don't need a schedule. So I personally think your schedule thing is probably just your environment.
Interesting, thank you for sharing! Would love to experience the free life some day :)
