I'm 29 now, but I was a lot like you at age 10. I think you'll like it here - you might find some material too advanced, but then I still do sometimes, so don't be too worried. You'll pick it up as you go along.

I can tell you stories of what I was doing at your age, but frankly I don't think it'd help much(since I did a lot of things wrong myself). The one piece of advice I'll give you that I think might actually help is this essay: http://www.paulgraham.com/nerds.html - more than anything else, it's what I wish I'd been able to read when I was your age. It does get better, and more quickly than you might expect.

Also, to a lesser extent, the ever-interesting Yvain posted this bit on his blog, which might help explain why what teachers do bugs you so much:

When I was a student, I hated all my teachers and thought that if they just ditched the constant repetition, the cutesy but vapid games, the police state attitude, then everyone would learn a lot more and school would finally live up to its potential as “not totally incompatible with learning, sometimes”.

And then I started teaching English, tried presenting the actually interesting things about the English language at a reasonable pace as if I were talking to real human beings. And it was a disaster. I would give this really brilliant and lucid presentation of a fascinating concept, and then ask a basic question about it, and even though I had just explained it, no one in the class would even have been listening to it. They’d be too busy chattering to one another in the corner. So finally out of desperation I was like “Who wants to do some kind of idiotic activity in which we all pick English words and color them in and then do a stupid dance about them??!” (I may not have used those exact words) and sure enough everyone wanted to and at the end some of them sort of vaguely remembered the vocabulary.

By the end of the school year I had realized that nothing was getting learned without threatening a test on it later, nothing was getting learned regardless unless it was rote memorization of a few especially boring points, and that I could usually force students to sit still long enough to learn it if and only if I bribed them with vapid games at regular intervals.

Yet pretty much every day I see people saying “Schools are evil fascist institutions that deliberately avoid teaching students for sinister reasons. If you just inspire a love of learning in them, they’ll be thrilled to finally have new vistas to explore and they’ll go above and beyond what you possibly expected.”

To which the only answer is no they frickin’ won’t. Yes, there will be two or three who do. Probably you were one of them, or your kid is one of them, and you think everything should be centered around those people. Fine. That’s what home schooling is for. But there will also be oh so many who ask “Will the grandeur and beauty of the fathomless universe be on the test?”. And when you say that the true test is whether they feel connected to the tradition of inquiry into the mysteries of Nature, they’ll roll their eyes and secretly play Pokemon on their Nintendo DS thinking you can’t see it if it’s held kind of under their desk.
