I have been programming for most of my life, and am very engaged in the art and craft of it, but I have a very hard time answering superlative questions like "what is the weirdest bug you fixed" or "what project are you proudest of". mostly I enjoy projects while I'm doing them, but don't have the kind of memory that lets me compare old and new work and see which one I rated higher by whatever metric. also bugs in particular tend not to stick in my mind - I can ramble at length about fun architectural decisions or ad hoc DSLs, but bugs I mostly fix and move on; even if they were super interesting to debug at the time I tend not to remember them later on.
