Don't be pessimistic, even if that's true, without discipline you'll get nowhere, no matter how talented you may be. I think I'm somewhere on the other side of the spectrum. In high school everything just went okay by itself. I never had much to do to pass the exams for most subjects, I dropped the uninteresting ones later, those were also the ones I was less good at. Now I have the problem I've never really learned to study well and how to put myself to work at things without getting distracted. I now do have to study to pass my subjects, which still works for nearly all of them, but my average grade is clearly lower than back then. I have no idea if this helps, I'm not really good at cheering up people.
But hey, at least you're creative enough to come up with all those random PokéTrivia games!
