I respect these definitions, though 'definition' itself is to limit and rule out some reality so as to focus on some other.
To me, 'Perfection' would be without further need of anything, finished, complete. What else could it need, want or even accept, if it is actually perfect? And if it needs nothing, it is static. And what is static? Static is not life, not alive and changing as life does! Life is full of change, surprise and - life!
Therefore I don't wish for perfection, but for excellence, especially continuously excelling my own past performance. Excellence is a living, changing concept. As one improves, the standard of excellence simply expands. It's alive and good but unlikely to reach perfection, since that finishes it. So that is my quest - excellence.
I wouldn't be in the least surprised if the Universe itself - (and mankind in it) - is a major expression of boredom or dissatisfaction with status - (perfection) and of a robust desire for life and change - and surprise.
Perfection is a concept which humans can consider, but can neither know nor prove.
