There's two things that humble me on a daily basis, in no particular order: collaboration and testing. While I use all sorts of testing, I still write a good amount of unit tests. For whatever kind of tests I write: not a day goes by without tests or the act of writing them exposing bugs that would otherwise have moved on to the "next level". Doesn't mean they'd have ended up in production, but they'd still have been a lot more expensive to fix.
