To me, at the time, successful would have been getting a tenure-track position at a Tier 1 university, discovering something important, and never publishing anything that was intentional fraud (I'm OK with making some level of legitimate errors that could need to be retracted).

Of those three, I certainly didn't achieve #1 or #2, but did achieve #3, mainly because I didn't write very much and obsessed over what was sent to the editor. Merely being a non-fraud is only part of success.

(note: I've changed my definition of success, I now realize that I never ever really wanted to be a tenured professor at a Tier 1 university, because that role is far less fulfilling that I thought it would be).
