Is Perfection An Unreasonable Benchmark?

Oxford defines 'Perfect' as a verb as to make something completely free from faults or defects; the other defines it as 'make as good as possible' The two interpretations of the word are contradictory to each other. The former definition is important in theory, but the latter definition makes it an attainable goal. Neither my life nor my work is free from defects, but I also trust it's the best that’s possible. We cannot guarantee that it will be free from all faults, but can we have to make sure that it is the best solution possible?
