grandiosity and just knowing I am right about something?

I get really caught up in things I see as an injustice and feel like I can see clearly a way to change things. For instance, my school district (my son's in 3rd grade) is doing horribly as far as academically and the state is continuously cutting the budget. I think the superintendent is an idiot and sincerely is not doing things in the best interest of the students. Same thing with the school board, its like they are all just proud of themselves for being in a position of power, its like a social thing or something. Anyway, we are having some very specific problems and I honestly feel like I know the solution to a few of the things that are wrong. The problem is that I get really, really emotionally involved when I think like this and even if I am 100% correct, I'm pretty sure I come off looking like a lunatic, not to mention I piss people off because I point out where they are wrong. Mostly knowing my own personality and behaviors, I try to stay out of it all and just let things go. I hate having to let it go though because my son is directly affected by what's going on. So, how do I know if this is just me thinking I know everything and me really knowing a solution to this?

Does that make any sense? I didn't want to bore you all to death with the details of the problems...anyhow, when I get like this I get all hyper and talk fast and cannot slow down (which is where i think I tend to lose credibility).
