I learned that i know way less than i thought about the US tax system, and that it's inherently setup for people who have enough money to pay someone to do the taxes for them, and squeek every penny out of it. There's no way the average joe "gets it" in a meaningful way.

But maybe i'm just young and dumb. I'll be paying someone to do mine for the first time this year... it's just way over my head. Actually, maybe it isn't... and i'm just too afraid of screwing it up.
