I assume perfect derives from per facere (latin) in which case:

Perfect ~ it/he/she has created (or accomplished or any other synonym) through action.

I find value in viewing it as 'it' has created through action. Viewing 'It' as הַשֵּׁם (phonetically HaShem, Hebrew literally "the Name" (for G-D))

And subsequentially perceiving it as having realized הַשֵּׁם in existence through action, which I deem fully doable, and given the eternity it allows to create in, realizable with ease.
