I can't help but think that the conclusion being "whatever happens happens, and your actions have very little to do with what your life's going to be" is a very zen / taoism / asian philosophy cliché.
Maybe the reason the west is successful lies in the belief that individuals matters.
If that's the case, then i suppose the OP still has a long way to go.
Maybe there's a balance to be struck between the two ideologies: that seemingly insignificant individual actions can have profound effects, while also accepting the fact that there are infinite environmental variables that we have negligible control over which influence every single one of those actions.
i don't think you need to "accept" the fact that there are infinite variables, or that you're not all-that-powerful. It's pretty much a given, and it's something you realise at 2 year old, when you really want to play with that ball, or lift that rock, or pretty much anything grown up do, but you can't. And as you're growing up, nature is always there to remind you that you're nothing.
IMHO, the role of education in the most general sense (encompassing the cultural background you're evolving in) is to help you think that you need to keep trying to make a difference, and not give up, because maybe one time in your life you'll accomplish something, and that'll be worth it.

Most two year olds can't form complex sentences, and so have yet to be indoctrinated into their culture's ideologies. It seems like the context of this whole thread is moreso about economic ideology than basic physics.
