The problem is you can not learn math from public school teachers because almost all of them are not able to do math themselves, the very few you meet who can are usually teaching the top level honors classes in high school, so at best you are only getting exposed to it for your last few years. The problem is the kind of skill required to do math usually leads you somewhere else besides public school, and if you are going to teach its going to be college level.
Most of the time anyone who really learns math ends up teaching it to themselves. It can be tough to find self motivation if you are struggling at all so the only kids who like math are usually the ones that instantly grasp concepts, they can do the rote busy work in a few minutes and spend the rest of class day dreaming about math ideas or reading ahead in the textbook to sections they find interesting. This is where the love of math comes from.
