I can't agree with this more. I hated math as a kid, I could learn the concepts very quickly but was prone to silly errors. So I'd fail many tests and I thought I was bad at math and shouldn't bother with it. Later doing an Engineering degree I found out math was this amazing tool that could help you model systems and do amazing things. The practice I got while solving interesting problems helped me learn to stop making silly errors. It wasn't that I was bad at math it was that I wasn't interested enough to focus. I just couldn't figure out why this wasn't the way math was taught at high school?
