Break the crap out of everything. Your job is to make sure the code doesn't get to production if it isn't any good. You are the last line of defense to prevent that 01:00... "Today's release broke prod; we're rolling it back."

Learn new stuff whenever you can. (Right answers were not allowed but that makes this a wrong answer so it's allowed.)
