To do better or perform better than someone else, or to do more of something than before.
Formed from the prefix 'out-' meaning 'surpass' combined with 'do,' creating a compound verb in Old English that literally means 'to do beyond.' The meaning has stayed consistent since medieval times.
The phrase 'outdoing yourself' is interesting because it implies you're competing against your own past performance—humans are unique in measuring success against our previous selves rather than just the competition around us.
