I wasted years of my life believing I wasn't "good at math" or whatever platitude was popular with everyone. I rediscovered math long after school and it has been a marvel. I really wish I wasn't so convinced by a faddish belief that most people can't do math. It was just an excuse to ignore, and then of course you won't know what's going on. That's not you, that's your past ignorance.
It just took one person to speak up when everyone was jokingly trash-talking their own math skills. One normal-looking guy, not bookish or anything but tatted up and heavy-set with a big biker beard, broke in to the conversation and said "I actually really like math." All of a sudden I just felt so stupid and realized what I'd been doing to myself. High school me was literally a moron. At least I still had time to catch up.
